Sergeant Hendy was a policeman who appeared in Series 1 of Waterloo Road. He was portrayed by Seamus O'Neill.
Hendy is first seen after Andrew Treneman calls the police when Donte Charles steals Stephen's bus fare. Donte refuses to give it back so Andrew calls the police, leading to Donte getting arrested.
Hendy is seen again in the same episode when Donte's dad, Clarence Charles, assaults Andrew for taking Donte's phone.
