Three people have been arrested after a man died when a bridge collapsed during a shooting trip on a farm.
Brian Harwood, 73, was killed when an off-road vehicle pulling a trailer fell into a river in Roeburndale, Lancashire on Tuesday.
The Cumbria resident was pronounced dead at the scene after the wooden bridge, which was supported by scaffolding, gave way.
Two men in their 60s and 70s remain in hospital and in total there were 11 people in the shooting party, Lancashire Police said.
A 55-year-old man from Preston, as well as a 57-year-old man and a 52-year-old man from Lancaster were arrested on suspicion of gross negligence manslaughter.
They have since been released, but remain under investigation.

"Three men have been arrested and are assisting police with our inquiries.
"We are supporting the families of those involved and working with partners, including the Health and Safety Executive, to establish what caused the bridge to collapse.
