London: The British police have arrested a third man in connection with the terror attack on a packed London Tube train that wounded 30 people last week. Scotland Yard's Counter-Terrorism Command investigating the Friday attack arrested the 25-year-old from Newport, South Wales yesterday.

The Metropolitan Police said that an address in Newport is being searched in this connection. On Saturday, an 18-year-old man was detained at Dover port and a 21-year-old was arrested in Hounslow in west London.

Both suspects were being held under the UK's Terrorism Act and being questioned at a south London police station. The suspects have not been named officially but the 21- year-old has been identified locally as Syrian refugee Yahyah Faroukh.

Thirty people were injured during the attack in which an improvised explosive device was detonated on a Tube train at Parsons Green underground station during morning rush hour on September 15.
