AN UNMANNED tug boat crashed into an RNLI vessel before becoming lodged under Poole Lifting Bridge after it had been released from its moorings by a group of youths.

The incident on the evening of Friday, January 29, involved Poole Harbour Commissioner's 'Rough Ryder'.

At around 9.11pm the boat reportedly became stuck under the bridge after it had been set loose.

Dorset Police said following enquires it was believed that four young people breached the security fence at Poole Quay and released the boat from its moorings.

The heavy vessel floated into the channel, colliding with the RNLI launch and coming to rest under the lifting bridge.
