Man, 29, arrested in police raid over racist traffic-cone attack

Ch Supt Emma Croft, the divisional commander for Glasgow, is overseeing the police investigation into the recent disorder.

"Members of the public might consider that it's one arrest following something that happened two weeks ago," she said.

"But please be assured that the methodical nature of the inquiry takes time and we'd rather have a clear case for prosecution."

She told BBC Scotland News that officers had trawled through a "significant amount of footage" which identified people they wanted to speak to.

She said the nature of the other alleged offences was "similar" to the traffic-cone attack, adding: "Unfortunately a lot of it had a racial tendency to it which is obviously of great concern to us."

Ch Supt Croft said that since June, police had arrested 56 people across Scotland for being involved in "incidents in and around protest that have amounted to criminality".

She warned that more arrests were expected.

"I think we're all feeling pretty disgruntled with the levels of division within our communities," she said.

"So it's absolutely key the public see the level of priority and commitment we're putting to these types of inquiries.

"Only when we can get these individuals rooted out and identified to the court will our public feel like they are at rest with all of this."
