Canoeists and dog walkers are being advised to steer clear of a stretch of the Grand Union Canal in Northamptonshire after a series of attacks by an aggressive swan nicknamed 'Tyson'.
The swan's flown at canoeists, violently flapping its wings, and has even pecked some boat users on the Grand Union Canal at Bugbrooke near Northampton.
It's thought Tyson is being so aggressive now because it's the mating season. He is often seen with his other half around the canal and The Wharf pub.
Pictured is Joe Davies, a chef at The Wharf pub, who was attacked while kayaking on the canal.
Tyson was given his name by Linda Sgoluppi, who lives beside the canal and asked her Twitter followers what name she should give him.
