A teenage boy has been slashed in the face metres away from a north London police station.
The 17-year-old was attacked on High Road in Tottenham at about 6.05pm, police said.
Officers said the boy was attacked by a Betfred shop.
Blood was being cleaned from the pavement outside a taxi office opposite Tottenham Police Station, around 160 metres down the road.
Cordons have been set up at both locations.
An officer at the scene said a man had received facial injuries after "an altercation between two young groups," and that the two cordons were linked.
The boy was treated at the scene by the London Ambulance Service staff, who assessed the injury to be non-life threatening, and taken to an east London hospital.
No arrests have been made.
