A 32-year-old man from Cospicua was arrested yesterday afternoon on suspicion of theft in Floriana.
A police constable was working in Floriana when he saw the man running and carrying a box.
The police said the constable ran after the man - who threw away the box which contained a portable DVD player - and arrested him.
The man had just stolen the DVD player from another man at the Valletta market, the police alleged.
They also said the Cospicia man was carrying a flick knife and was being held for further investigations.
