Police descended on a road in south London this afternoon where an armed man was holding a woman against her will.
Officers were called just after 1pm on Wednesday to reports of a woman in her 20s in danger at a home.
She was being prevented from leaving a property in Daysbrook Road, Streatham, by a man armed with a knife, the Met Police said.
Police arrested the man at the scene more than six hours after the incident began.
Officers said the victim and the suspect were known to each other.
Police said the woman was not injured during the incident.
Video from the scene shows a number of police cars and an ambulance behind police tape on the junction with Palace Road.
A police spokesman said specialist units had been dealing with the incident.
Safety cordons have now been lifted.
