Police have arrested a 24-year-old London man and recovered a vehicle from a London address following a hit and run in Hove.
The incident happened at the junction of Church Road and Sackville Road in Hove at 11.09pm on Christmas Day.
The man has been released on bail until February while enquiries continue.
The collision involved a blue Skoda Octavia taxi and a silver Vauxhall Insignia, which left the scene.
A teenage boy who was a passenger in the taxi suffered serious head injuries and has since undergone surgery in an effort to save the sight in his right eye.
The taxi driver sustained minor injuries.
A 16-year-old boy had glass enter his eye following a hit and run in Brighton where his taxi collided with a car that sped off.
The boy was a front-seat passenger in the taxi which crashed shortly after 11pm on Christmas Day at the junction of Church Road and Sackville Road in Hove.
The blue Skoda taxi was travelling east to west along Church Road when a silver Vauxhall Insignia saloon travelling south to north along Sackville Road collided with its nearside.
The taxi went out of control and mounted the pavement.
The teenager from Southwick suffered head injuries, including glass fragments entering his eye and the driver suffered whiplash- both were taken to hospital by ambulance.
