Police Scotland just sent its biggest call for help since Trump visited Scotland

Emergency crews in Glasgow were attacked with fireworks a few hours ago.

And a police car got torched while they were at it.

Here's what happened. Police and an ambulance crew got called to Greenside Street in Glasgow, just before 8pm. Somebody had reported an injured man.

While they were there, both crews came under fire. Fireworks. A police vehicle was set alight and badly damaged.

One police officer was hurt. One ambulance worker was hurt too. Police Scotland says both injuries were minor.

So how many people have been arrested over this? Well, that depends which Police Scotland statement you read.

On the night, Police Scotland told reporters one man had been arrested over the Greenside Street attack. Just one.

Then wire copy carried by Brit Brief and the Stratford Herald reported seven arrests overall.

Then Police Scotland put out its own follow-up statement. That one said three arrests had been made to date, with inquiries ongoing.

One, seven, three. Three different numbers, from three different moments, covering three different things — one incident, a nationwide count, and a later running total. They don't add up, and nothing published so far explains why.

And Glasgow wasn't the only trouble spot.

In Edinburgh, police got a call about youths blocking Oxgangs Road North, around 5.30pm. Officers who turned up had fireworks set off at them. Nobody was hurt there. Nearby, around Colinton Mains, bins were turned over and set on fire in the road. Firefighters had to pull back from bin fires in the south of the city after facing abuse.

Police Scotland says there was trouble in parts of Glasgow, in Sighthill in Edinburgh, in Clydebank, and in West Lothian too.

Chief Superintendent David Robertson of Police Scotland says quote "an unacceptable number of incidents" involving attacks on police and emergency service colleagues with fireworks and other projectiles.

That's a senior officer saying this happens every single year.

He says investigations are now underway to find those responsible.

Now, here's why the deployment was so big. Police Scotland called in officers from four forces in England and Wales — Avon and Somerset, Hampshire, Hertfordshire and South Wales. That's the force's biggest request for help since Donald Trump visited Scotland last year.
