CCTV footage has been handed to police after a gang of teenage thugs hurled bricks and foul-mouthed abuse at fire crews responding to an incident in Hough Green.
Officers from Green Watch at Widnes fire station were called to Arley Drive on Friday afternoon where they faced a hail of missiles.
The gang also threatened the officers with bottles and costly damage was caused to one of the fire engines.
Firefighters warn that the thugs' days may be numbered as all fire engines in Halton are now fitted with CCTV equipment which captured high quality footage of the gang.
The tapes have been passed to police who will scrutinise the footage in a bid to identify the culprits.
And police have been taking detailed statements from the Green Watch officers who were targeted.
A spokesman at Widnes fire station said: 'We are deeply concerned about the attacks on fire crews.' Firefighters have been attacked by thugs several times. Gangs deliberately light fires then lie in wait in bushes, bricks and bottles at the ready.
One attack happened at St Michael's Golf course and resulted in one firefighter being struck on the head with a brick.
Paul McGugan, commander at Widnes fire station, said the officer could have been killed or seriously injured had he not been wearing a helmet.
Fire crews now have required police escorts when responding to emergencies in parts of the town, including Ditton, a known black spot.
