More than 100 police officers are involved in the search for three brothers kidnapped by their father from a foster home Coulsdon.

Detectives don't know whether Imran Safi, who's from Afghanistan, has taken them abroad, but an alert's been sent to all ports.

They were abducted from their foster carer at knifepoint a week ago.

Eight people from Croydon have been arrested and bailed in connection with the inquiry.

Here's Metropolitan Police Commander Jon Savell.
