Marine Policing Unit
The Marine Policing Unit (MPU) are responsible for policing 47 miles of the River Thames between Dartford and Hampton Court. We also support our Borough police colleagues by responding to incidents on the 250 miles of canals and other waterways within London.
The Marine Police have been protecting life and property and preventing crime on the Thames since 1798. Policing on the Thames today is very different.
Project Kraken and Marine Watch
Register your boat, register your property. By working together we can identify suspicious behaviour, reduce crime and make London’s waterways safe.
What we do
The MPU is a 24/7 frontline policing unit with a wide range of skills and a strength of 76 officers. We operate from our base on the River Thames at Wapping.
