Britain ramps up security at major events after 11 suspects detained over Manchester attack

Security at major public events across the country on Saturday has been ramped up after Monday's terror attack in Manchester that left 22 dead.

Thirteen people have now been arrested in connection to the suicide bombing at an Ariana Grande concert at Manchester Arena. Two were released without charge, with a further 11 remaining in custody.

On Friday evening, Police arrested a 44-year-old man after storming a bus in Rusholme, about two miles south of the city centre. Passengers told Manchester Evening News that at least six officers boarded the bus and told everyone to leave.

"I saw plain-clothed policemen, uniformed and some in face masks with machine guns," an eyewitness told the publication.

Further addresses were being searched on Saturday morning in Manchester.

Meanwhile, Britain's top counter-terrorism officer has said police are making "fantastic progress" in tracking down Salman Abedi's terror network, and urged Brits to "enjoy yourselves" this weekend.
