REPUBLIKA.CO.ID, LONDON -- British police said on Tuesday they had arrested a man at London's Heathrow airport in connection with the investigation into the suicide bombing on a concert hall in Manchester last month which killed 22 people.
"The 38-year-old was arrested on suspicion of offences contrary to the Terrorism Act and remains in custody," Greater Manchester Police said in a statement on Twitter.
"The arrest was planned beforehand and there was no direct threat to the airport."
Meanwhile, Irish police have arrested a second person in connection with Saturday's attacks in London which killed seven people and left dozens wounded, British broadcaster Sky News reported on Tuesday.
Irish Prime Minister Enda Kenny said on Monday that one of the London attackers, Moroccan Rachid Redouane, had lived in Ireland but did not attract police attention.
A man arrested earlier in Ireland over the attacks has been released without charge.
At least seven people were killed when the three men rammed a van into pedestrians on London Bridge and then stabbed revellers in nearby bars.
