Ali Harbi Ali, the son of an ex-media adviser to a former prime minister of Somalia, has been arrested by British police under antiterrorism laws following the killing of lawmaker David Amess, a source close to the investigation and British media said.
Amess, 69, from Prime Minister Boris Johnson’s Conservative Party, was knifed repeatedly as he met constituency voters in a church on Friday in Leigh-on-Sea, east of London.
The killing took place five years after the murder of Jo Cox, a lawmaker from the opposition Labour Party, and has prompted a review of politicians’ security.
Police said they had arrested a 25-year-old British man at the scene on suspicion of murder and have said it is believed he acted alone. They have not named the suspect but used additional powers under antiterrorism laws to detain him until October 22.
A British source close to the investigation named Ali Harbi Ali, a British citizen, as the detained suspect.
Harbi Ali Kullane, the father of Ali Harbi Ali, told The Sunday Times that his son had been arrested in connection with the murder.
“At this particular moment we are going through (an) unprecedented and horrific situation,” Harbi Ali Kullane, a former adviser to Hassan Ali Khaire, a former Somali prime minister, told Reuters in an email when asked about this.
“Due to the ongoing early investigation I am obliged and commanded not to talk about it,” said Harbi Ali Kullane, who is a former director of the Somali government’s media and communication department.
British police were on Sunday searching an address in north London linked to Ali Harbi Ali, Reuters reporters said.
Amess’ family said they were “absolutely broken” and urged people to pull together.
“Set aside hatred and work towards togetherness,” they said in a statement released via London police. “Whatever one’s race, religious or political beliefs, be tolerant and try to understand.”
Interior minister Priti Patel said Britain is looking at how to boost the security of lawmakers.
“Within that there are other options that are being considered such as when you hold your surgeries, could you have officers or some kind of protection…?” she told Sky News on Sunday, referring to meetings British lawmakers have with their constituents.
