The bronze bull statue at the entrance to Birmingham's Bullring centre has been attacked for the second time in a week.
Centre managers said a person was arrested at the scene of the latest attack, which happened in the early hours of Saturday, and was being questioned.
West Midlands Police confirmed yesterday that an 18-year-old man had been arrested on suspicion of criminal damage and bailed pending further inquiries.
The latest attack comes just a week after a vandal wearing a hooded top struck on February 5 and scrawled letters into the body of the six-ton bull using an ice skate.
Yesterday, sculptor Laurence Broderick said the only way to protect the statue from attacks might be to move it inside the shopping centre.
Mr Broderick said: "People who damage it are going to see it as a publicity stunt, a statement. It's impossible to have security stationed around it 24 hours-a-day."
