London (AFP) - Police in Britain said on Wednesday (Dec 23) they had arrested a 31-year-old man in London in connection with suspected "extremist Islamist terrorism".
"The man was detained by officers at a business address in south London" on Tuesday, London's Metropolitan Police said.
"The arrest is being linked to extremist Islamist terrorism," it said, adding that police had also searched a residential address in south London.
The man is suspected "of being involved in the commission, preparation or instigation of acts of terrorism," the statement added.
Contacted by AFP, the police could not give further details.
