River Thames [SEP] Police and lifeboats
The river is policed by five police forces. The Thames Division is the River Police arm of London's Metropolitan Police, while Surrey Police, Thames Valley Police, Essex Police and Kent Police have responsibilities on their parts of the river outside the metropolitan area. There is also a London Fire Brigade fire boat on the river. The river claims a number of lives each year. As a result of the Marchioness disaster in 1989 when 51 people died, the Government asked the Maritime and Coastguard Agency, the Port of London Authority and the Royal National Lifeboat Institution (RNLI) to work together to set up a dedicated Search and Rescue service for the tidal River Thames.
