One of the suicide bombers behind the Sri Lanka suicide attacks was former UK student Abdul Lathief Jameel Mohamed, according to security sources, ONA reports citing Sky News.
Mohamed is believed to have studied in the southeast of England at some point between 2006 and 2007 - and later did a postgraduate course in Australia, before returning to settle in Sri Lanka.
The terrorist was one of nine who carried out a series of blasts targeting churches and hotels in the country, killing 359 people .
During an earlier news conference on Wednesday, deputy defence minister Ruwan Wijewardene said all nine of the bombers - eight of whom have been identified - were well educated and from wealthy families.
One of the them was a woman, who killed herself as police raided her home, and another - who targeted the Shangri-La hotel - has been identified as factory owner Insan Seelavan.
The woman, thought to be the wife of one of the bombers, blew herself up at the home of her father-in-law, who has been taken into custody.
It is reported that his two sons were also bombers.
Police have so far made 60 arrests, all of whom are Sri Lankan nationals, and 32 people remain in custody.
The prime minister added: "Some of the suspects are on the run.
"Some of those suspects are armed and dangerous. There are still explosives and militants out there and the police are looking for them."
