A man and a woman have been charged with the attempted murder of a police officer who was stabbed during an operation in east London.
Andrew Beadie, 20, and Janine Morris, 34, were also charged with affray in connection with the incident.
The male officer, who was knifed in an alleyway near a pub in Bow on Tuesday, remains in hospital, Scotland Yard said.
The officer, who was in plain clothes when he was deployed on the planned operation, received non life-threatening injuries in the attack.
Beadie, of Basildon, Essex, and Morris of Bow, East London, who was also charged with assisting an offender, will both appear in custody at Barkingside Magistrates' Court on Monday.
A 17-year-old boy who was arrested on suspicion of attempted murder was bailed until a date in late January.
