A woman was hospitalised and a man was arrested following an argument between them in a St Paul's Bay apartment last night.
The police said they were alerted about the case at midnight in Triq Mozzolla.
The argument involved a 25-year-old woman resident in St Paul's Bay and a 27-year-old man from Floriana.
The woman was found to be seriously injured and was hospitalised. The man fled the scene but was later arrested.
Investigations are continuing.
