A MOB hurled missiles at police in Thornton Lodge last night.
Officers came under fire from a hail of bricks and fireworks after being called to reports of an arson attack at Thornton Lodge Community Centre.
It was the third fire at the centre since Sunday night.
Police reinforcements wearing helmets and protective clothing were called in to disperse the gang of men and youths.
This morning, detectives appealed for calm and promised talks with community leaders.
Det Chief Insp Colin Prime said: "This would appear to be an isolated incident.
"We are appealing for calm in the area and will be speaking today to community leaders.
"Anyone with any information about last night's incident should contact the Huddersfield police on 01484 436722".
Police were alerted just after 8.20pm last night when there were reports of a fire at the Community Centre in Brook Street.
Fire crews also arrived at the centre, which houses a number of local groups and organisations.
The fire was confined to a window and a mattress on the floor just inside the building, but smoke-filled a room and corridors.
Police had bricks and fireworks thrown at them.
A police spokeswoman said: "There were no injuries, but several police vehicles were damaged by bricks.
"We mounted high-visibility police patrols throughout the area and the group dispersed".
Two local men in their 20s were arrested for alleged public disorder offences and were being questioned at Huddersfield police station today.
Two more men, also in their 20s, were arrested by police investigating the arson attack on the centre. They, too, will be questioned today.
