Listen to our interview with area manager for service delivery at West yorkshire Fire Service Chris Kirby, who's been speaking to Pulse 1 & Pulse 2.
Fire chiefs have described another attack on a crew in Bradford as 'disappointing' and 'frustrating'.
They had glass bottle thrown at them and a brick hurled at the fire engine in Warrenton Place in Lidget Green on Monday evening.
It follows a series of incidents across West Yorkshire at the end of 2017, especially around Bonfire Night.
Area manager for service delivery Chris Kirby told Pulse 1 & Pulse 2: "Some people just see our crews as an authority figure. It's normally bricks and bottles and in some cases fireworks that are directed at our firefighters.
"It can be extremely dangerous when they're just trying to do their job. For certain members of the community to turn on us, is extremely frustrating.
"We condemn it and we're working with West Yorkshire Police to bring offenders to justice."
Firefighter John Mello was on shift in Lidget Green and was winding up the hose. He said: “I was bent down when a large bottle came across and smashed on the ground in front of me.
“A brick hit the fire engine windscreen and two youths ran off.
“Fortunately I was not hurt and the fire engine was not damaged but I realise I was lucky. It’s a real shame that firefighters have to face this kind of aggressive behaviour when they are simply trying to help keep communities safe.”
