I suspected as much reading in between the lines of first Cressida Dick's comments, but more important, those of Prime Minister Boris Johnson as he arrived for tonight's Cobra meeting.
This is from the 10pm BBC TV news. The attacker on London Bridge today (no name yet) is a previously convicted terrorist, who was apparently still serving part of his sentence. Hence the concern of Boris Johnson about what to do with convicted terrorists if they still pose a danger.
The London Evening Standard has a written report. Of course he was Islamic - the murders were just their pattern.
The knife-wielding terrorist who killed two people before being shot dead by police was known to authorities and had connection to Islamist terror groups, a security source has said.
The attacker, who was wearing a fake suicide vest and has not been named, was killed on London Bridge on Friday afternoon in full view of horrified onlookers.
Prime Minister Boris Johnson said the deaths were heartbreaking and hinted the suspect had previously been convicted of terror offences.
According to The Times, the attacker had been released from jail after he agreed to be monitored by authorities.
The paper said he was attending a Cambridge University conference on prisoner rehabilitation being held at Fishmongers' Hall in the City of London and "threatened to blow up" the building.
The attacker is understood to have been wearing an electronic tag when he staged the attack after being released from prison for terrorism related offences.
Speaking before chairing a meeting of the Government's emergency committee Cobra, Mr Johnson said he had "long argued" that it is a "mistake to allow serious and violent criminals to come out of prison early and it is very important that we get out of that habit and that we enforce the appropriate sentences for dangerous criminals, especially for terrorists, that I think the public will want to see".
Metropolitan Police Commissioner Cressida Dick, during a press conference, refused to confirm whether or not the suspect was known to police.
More from the Mirror
A security source confirmed to the PA news agency he was known to police and had connections to Islamist terror groups.
A maintenance worker who witnessed the London Bridge knife attack claims he was told the assailant had been in prison for terrorism offences. Jamie Bakhit, a 24-year-old from Purley, Croydon, said he spoke to one of the men who helped wrestle the knifeman to the ground after they were taken to the Salvation Army headquarters to be interviewed by police.
He told the PA news agency: "The guy who was on top of him said he [the attacker] had been in prison for terrorism, apparently. Some of the guys who were on top of him were ex-prisoners and they had all been in the Fishmongers' Hall. The guy told me he was in prison with the attacker."
"...As I got on the bridge armed police pulled in front of me. There were already four pedestrians on top of the guy on the floor. One of them [pedestrians] was shouting 'shoot him in the f***ing head'.
A guy who was with us at Fishmongers Hall took a 5’ narwhale tusk from the wall and went out to confront the attacker. You can see him standing over the man (with what looks like a white pole) in the video. I thought it was a broomstick. We were trying to help victims inside but that man’s a hero
