Police dog van attackedpublished at 10:25 British Summer Time 16 September
Crowcroft was involved in trouble at about 12:55 BST, before fires were being set outside the hotel.
A police dog van was being deployed to the location as it had a loudspeaker, and it was hoped a chief inspector could speak to the crowd and ask them to disperse.
However, when he began to speak, the crowd turned to the van and started to rock it, "trying to overturn it", Ms Hollis tells the court.
A PC in the van feared the vehicle might be tipped and set alight, so he began to slowly try and drive away from the area, we hear.
