Ukbd Times Desk:
The third London bridge attacker was today identified as a 22-year-old of joint Moroccan and Italian nationality who was stopped last year attempting to fly to Syria.
Youssef Zaghba, who was born in Fez, was detained at Bologna airport, as he tried to board a plane to Turkey.
He planned to travel from there to join Islamic State in Syria.
IS propaganda films were reportedly found on his phone.
It is understood that he remained at liberty after an investigation by the Italian authorities found insufficient evidence to prosecute him.
But warnings were reportedly given to both the British and Moroccan authorities.
The development came as armed police carried out a raid in Ilford in the early hours with detectives continuing to trace associates of the terror gang that committed the London Bridge atrocity.
Pakistan-born Khuram Shazad Butt, 27, and Rachid Redouane, 30, were named yesterday as the other two attackers who used a van to mow down pedestrians on the bridge and then launched a stabbing rampage in Borough Market, killing seven and injuring dozens more.
It also emerged today that killer Butt had been a London Underground trainee and was allowed to work at two of the busiest stations despite appearing in a TV film on British jihadis and being on the radar of MI5.
He was based at Westminster and Canada Water stations during his training last year and was only sacked because of his absences.
A picture obtained by the Daily Mail showed him on duty at West Kensington station.
A former colleague said: “It was well-known that he had appeared in this extremist documentary — but he was asked to leave London Underground not because of that, but due to poor attendance.”
Scotland Yard confirmed yesterday that Butt was known to the security services and investigated by MI5 in 2015 but was downgraded as a priority because there was no evidence that he was planning an attack.
Transport for London confirmed that Butt worked on the Underground for just under six months as a trainee customer services assistant, leaving last October.
Today there were reports that police in Pakistan had carried out raids on his home and another business there. source:evening standard
