Police officers who arrived at the block of flats where a woman fell to her death from the17th floor were attempting to recall a convicted thief to prison.
Scotland Yard faces an inquiry from the police watchdog after the incident.
It's understood that the thief had been convicted in connection with three street robberies in London in 2009, and was out on licence after serving part of their sentence, Scotland Yard said.
