A man being held in police custody attempted to self-harm but was stopped before he could do any damage to himself, the police said in a statement on Sunday.
The 59-year-old was being held at police headquarters in Floriana at the time. A police officer intervened just in time and the man was unhurt. He was nevertheless taken to Mater Dei Hospital as a precautionary measure, the police added.
Investigations into the incident are under way, they said.
