British police make more arrests connected to London attack

British counterterrorism investigators search two homes and detain “a number” of people in the investigation into a van and knife terror attack in the heart of London that left seven people dead.

London’s police chief says the attackers have been identified, but the names haven’t been released. At least 12 people were arrested Sunday, including five men and seven women ranging in age from 19 to 60.

Metropolitan Police Commissioner Cressida Dick says she won’t release further details in what she describes as a fast-moving investigation, including whether authorities were familiar with the men before the attack.

IS has claimed responsibility for three attacks in Britain since March, and Dick describes the recent wave of violence as “unprecedented in my working life.”

“We in this country have faced a terrorist threat throughout my life — it changed and morphed and we will change and adapt to what appears to be a new reality for us,” she says.
