DUBLIN, June 5 (Xinhua) -- Irish police were investigating the background of one of the London Bridge attackers after documentation showed he had spent some time in Ireland, public broadcaster RTE reported on Monday.
Rachid Redouane has been named by British police as one of the three men who carried out the attacks, which killed seven victims and injured dozens more in the London Bridge area on Saturday night.
British police said the 30-year-old man is of Moroccan and Libyan descent.
RTE reported Redouane was identified after a documentation check in Britain found he had lived in south Dublin for some time.
An identity card, issued by Irish immigration authorities, was found after he was shot dead, it said.
He married a British woman in Ireland in 2011 before moving back to Britain, according to RTE.
Under European Union treaties, Ireland grants working visas to people outside the EU who are in a relationship with an EU citizen, which appears to have been the case in this instance.
RTE also said the couple returned to Ireland for a short time in 2016 before separating.
But RTE quoted police sources as saying that the man was not previously known to police and had not come to their attention in relation to any crime or security issues.
Ireland has condemned the London terror attacks, describing the attacks as "sheer madness". Ireland said it will continue to work closely with Britain on security matters and prevention as far as possible.
Currently, the threat assessment level in Ireland is moderate, meaning an attack is possible but unlikely.
