Behaviour is the major factor when identifying a terror suspect, rather than ethnicity, a security expert told the Manchester Arena Inquiry.
Tony Holyland from the Security Industry Authority (SIA) said Salman Abedi’s actions on the night he bombed the venue should have raised suspicion.
Twenty-two people died in the attack on 22 May 2017.
Mr Holyland said Abedi’s “loitering”, the way he was dressed and his multiple visits would have been indicators.
