Police drone crashes into River Mersey

A drone used by police on Merseyside crashed into the River Mersey during a routine training exercise.

The Unmanned Aerial Vehicle (UAV), which was fitted with CCTV, apparently lost battery power while being flown by officers in Aigburth in February 2010.

Attempts to make an emergency landing failed and it crashed into the water. (more on bbc.co.uk)
