Morrissons alarms + Police + Fire engines

Does anybody know what went down at Morrissons last night? Alarms were going on and off until 4am, a fair few police cars and at least 2 fire engines were there from about 2am until after 4.

My neighbour saw police tape near the cash machine, and a forensics van this morning, but by 4pm, I saw nothing.

Yes we’re nosey, but I think we also have a right to know why those of us who live next door to them were kept awake until 4:30am this time round
