Manchester Police Chief Constable Ian Hopkins identified the suicide bomber responsible for the carnage as 22-year-old Salman Abedi and warned angry residents against any reprisals.
“We understand that feelings are very raw right now and people are looking for answers,” he said. “We will not tolerate hate towards any parts of our community.”
Police have also arrested a 23-year-old man in Manchester in connection with the attack, said Hopkins, who did not identify him.
Earlier, the Islamic State terror group claimed responsibility for the explosion that tore through fans leaving an Ariana Grande pop concert in Manchester.
