Is this the Berlin killer posing as a child when he entered Europe? Tunisian refugee believed to be Anis Amri is pictured among newly arrived migrants on the dock of Italy's 'island of hope' in 2011

Staring into the camera on the dock of Italy's 'island of hope', this is believed to be Europe's most wanted man after entering the continent pretending to be a child.

Weeks after landing in 2011, terror suspect Anis Amri, 24, was sentenced to four years in prison for burning down a migrant reception centre on the Italian island of Lampedusa.

Amri was on one of two boats that left the Tunisian port of Sfax in March 2011 - one vessel sank but the terrorist's ship made it safely to the Mediterranean island. 

Italian newspaper Corriere della Sera and other media outlets say the extraordinary photographs from five years ago are Amri, aged 19. 

MailOnline has chosen to blur the images because it cannot be categorically proved it is him.

Is it him? This photo also reportedly shows the ISIS terrorist among other young Tunisian asylum seekers

Instead of starting a new life in Italy, the career criminal turned to radical Islam and would event threaten to behead a Christian cellmate in Palermo after befriending extremists.

With nowhere to go after his release, ISIS recruiters offered him protection before convincing him to sneak into Germany as a Syrian refugee, a source within Tunisia's anti-terror police has revealed.

The source told MailOnline: 'Whatever he decided to do in Germany was started while he was in Italy.

'They gave him food and shelter and persuaded him to carry out a mission for them. It was in Italy that he was radicalised.

'He entered Germany posing as a Syrian refugee. He was a vulnerable young man and they showed kindness to him.'

Germany police have offered a €100,000 reward for the capture of Amri, born in Tatouine in Tunisia, who is accused of ploughing a 25-tonne lorry into crowds of people at a festive market on Monday, killing 12. 

The Tunisian asylum seeker's brother told how he was brought up in a poor, but strict Muslim family in Tunisia.

But as a teenager Amri began drinking and had a number of girlfriends, it is claimed. 

In 2011 he fled Tunisia to Europe to avoid being jailed for robbery and violence offences in his home country. Amri was sentenced to five years in prison in 2011 - but left the country before he could be jailed. He arrived illegally in Italy in early 2012 as a fugitive from justice.

His father Mustapha said he was later jailed for arson in Italy when he burned down a migrant reception centre during a violent protest on the island of Lampedusa - the entry point into Europe for hundreds of thousands of migrants fleeing north Africa and the Middle East.

Amri was one of a number of migrants who set fire to their mattresses, which burned the migrant centre holding 1,200 refugees to the ground.

Many refugees were given permission to travel freely through Europe but Amri was ordered to stay in the overcrowded camp because he claimed to be an unaccompanied minor, reported. 

Lampedusa's then-Mayor Bernardino De Rubeis claimed he had repeatedly warned the government that tensions between the migrants were reaching breaking point 

Jail term: Amri fled Tunisia where he was facing a five year jail term for robbery. After his release from prison for his part in the migrant riots on Lampedusa in 2011, security sources in in Tunisia say he was radicalised by ISIS fanatics while he was sleeping rough in Italy.

The fire, which destroyed three buildings, was reported to have been started by Tunisians, including Amri, who were ordered to return home after some were ordered to return to Tunisia. 

Amri, a lifelong criminal who who arrived in Germany that year, was released four months early from his four year sentence. He arrived in Germany in July 2015 and remained under the surveillance of the intelligence services for several months.

He had been arrested three times this year and his asylum application was rejected, but deportation papers were never served and he disappeared.

The Tunisian radical was known to be a supporter of Islamic State and to have received weapons training. He tried to recruit an accomplice for a terror plot - which the authorities knew about - but still remained at large.

He was under investigation for planning a 'serious act of violence against the state' and counter-terrorism officials had exchanged information about him last month. 

THIS IS VENGEANCE FOR AIRSTRIKES AGAINST MUSLIMS - WE WILL SLAUGHTER YOU LIKE PIGS

Ranting into a camera as he shoots a selfie-style video, this it the Berlin lorry killer pledging allegiance to ISIS and vowing to punish 'pig eaters'.

Anis Amri can be seen wearing a dark jacket and headphones and standing on a bridge over a river as he delivers his chilling speech, warning he wants to become a martyr.

The brainwashed 24-year-old went on to slaughter 11 revellers enjoying a Christmas market in the heart of Berlin on Monday night.

Anis Amri can be seen wearing a dark jacket and standing in front of a river as he delivers his chilling speech, warning he wants to become a martyr.

According to the respected SITE website which monitors terror activity, Amri says he will target 'pig eaters'. 

He also says: 'I pledge my allegiance to the caliph Abu Bakr Al Baghdadi. I pledge to participate in jihad against the enemies of Allah.

'My message to those infidels who bomb Muslims everyday - we are going to slaughter you like pigs. We will avenge the Muslims you killed and continue to kill.

'And to my Muslim brothers all over the world, fight for this religion whether in your countries or in Europe if you live there, as mush as each of you can.' 

It was unclear exactly where or when the video was filmed.

As well as his pledge of allegiance, Amri declared his desire to avenge Muslims killed in air strikes and called for attacks against "Crusaders".

Amaq had earlier said the man shot dead by Italian police near Milan on Friday carried out the Berlin attack. 

Releasing suicide videos of terror attackers after their deaths is a common tactic by ISIS.

In July fanatics were shot dead after murdering an elderly priest at a church in Normandy. A day later, ISIS news outlet Amaq published a video of the two perpetrators pledging allegiance to ISIS leader Abu Bakr al-Baghdadi.
