Five women and a girl aged 14 have been sexually assaulted while walking alone late at night in Crouch End, Archway and Stroud Green.

The attacker is described as wearing dark clothing and riding a moped with a box attached to the back. Police suggest he could be working as a delivery driver, courier or fast food worker.
The victims’ ages ranged from 14 to 29. All but one of the assaults happened after 10pm.
Officers have advised the public to be careful walking alone in the area at night and to report any suspicious activity to police immediately.
