This happened Thursday in Plymouth, where officers walking the streets were alerted to a commotion.
It is not known how serious the bird’s injuries were.
A police spokesperson told Plymouth Live that the man admitted to the scene that he had used drugs.
They said, “He put his teeth in it before he threw him on the ground.
“The officers saw the incident and immediately went to the scene and detained and took details of him.
“Around this time, the man said he was under the influence of drugs and it was decided that he should be taken to Derriford hospital for treatment.
“The seagull was clearly injured by the incident but flew away before we could verify its well-being.
“We don’t know what happened to him afterwards. ”
Many gulls can be considered pests, but they are protected by the Wildlife and Countryside Act 1981.
The ignorance that birds are protected is not a defense under the law.
It is illegal – except under license – to take, injure or kill wild birds or to interfere with their nest or eggs.
The maximum penalty, if convicted, is six months in prison or a fine of £ 5,000.
Police said the case was still under investigation and were calling on other witnesses to the incident.
