MONTREAL — Francis Boucher, who walked out of a Montreal jail on Monday, was back in custody early Friday after turning himself in to authorities.

The son of former Hells Angels boss Maurice (Mom) Boucher surrendered while accompanied by his lawyer, Dimitrios Strapatsas.

Boucher, 39, a former member of the Rockers, a Hells puppet gang, had walked out of Montreal’s Bordeaux jail in broad daylight Monday.

He was serving a 117-day sentence for uttering death threats against police officers — a sentence due to be completed at the end of May.

Boucher appeared shortly after midnight at the jail, where he was immediately arrested by Quebec Provincial Police. He was expected to appear in court later Friday to face at least one charge related to his leaving the facility.

Boucher was previously sentenced to 10 years behind bars for gangsterism, conspiracy to commit murder and drug-trafficking.

On Wednesday, Strapatsas had made a public appeal to his client, urging him to surrender as quickly as possible.

There has been speculation Boucher was able to leave the jail with help from someone on the inside but Strapatsas said Wednesday that he did not believe that was the case.

During Wednesday’s question period in the national assembly, the opposition asked Public Security Minister Lise Theriault why Boucher was on the run.

She replied that two inquiries were underway — one administrative and the other by provincial police.

A Quebec prison guard was suspended the day after Boucher left the jail.

Maurice Boucher was a household name in the late 1990s and early 2000s during a bloody battle between the Hells and the Rock Machine.

Boucher was sentenced to life in prison in 2002 after being convicted of two counts of first-degree murder in the killings of prison guards that were aimed at destabilizing the justice system.
