A GANG of up to 100 bikers wearing Halloween masks terrorised pedestrians and motorists as they tore through the streets of Trafford on off-road bikes and motorcycles.

Witnesses said between 50 and 100 bikes sped through the streets in a convoy, causing chaos on Trafford's roads by riding in a dangerous manner.

Police received numerous reports of the off-road bikes, motorcycles and mopeds surging through traffic and intimidating drivers.

Though not all the riders acted recklessly, many of the bikers wore Halloween masks and were seen speeding, weaving in and out of traffic, riding in the wrong direction and on the pavement, and performing stunts before oncoming traffic.

Eyewitnesses said the group brought traffic to a standstill 

The group's dangerous and anti-social behaviour was witnessed across Trafford, Salford and Manchester city centre.

By 10.15pm, the group had dispersed and there were no further reports made to police.

Since the incident, officers have been carrying out enquiries to identify those responsible.

Superintendent Howard Millington, of GMP’s Salford Division, said: “We’ve been carrying out numerous lines of enquiries to identify the riders in the group who were seen to be driving irresponsibly.

“Not all of the riders in the group drove recklessly, but those who did posed a real risk to themselves and members of the public.

“This kind of behaviour is a genuine concern for many residents in Manchester, and I’d like to reassure the community that we are focused on tackling this issue and finding those responsible.

“We will have extra officers on duty this evening and I would encourage the public to remain vigilant and to report any illegal activity to police right away.”
