The former East 17 singer Brian Harvey has been arrested over allegations he sent “malicious communications”.
Scotland Yard said they had been called to a house in Walthamstow, east London after reports that a man was threatening to harm himself.
He did not suffer any injuries.
Police said they had performed a welfare check on a man in his 40s, and then arrested him. Following a physical examination where he was deemed fit, he was taken into police custody.
In a statement, the Metropolitan Police said: “Following a mental health assessment at hospital, the man has been taken into police custody where he remains.”
In a now deleted video, Harvey live-streamed his arrest and showed police arriving at his property, asking him if they could go inside and talk to him.
Harvey is known for being part of the 90’s pop group East 17, later E-17, who achieved Christmas number one in 1994 with Stay Another Day.
