People are being reminded to "respect the emergency services" after bricks were hurled at firefighters ahead of Halloween.
Crews were tackling a fire involving a number of wheelie bins in Mersey Park in Tranmere on Thursday night when they had bricks thrown in their direction.
Thankfully no one was injured during the incident, which has prompted Merseyside Fire and Rescue service to issue a warning to people this weekend.

The fire service tweeted on Friday: "We shouldn't have to tell people not to attack our firefighters & staff.
"We shouldn't have to say that throwing bricks & fireworks at emergency services isn't 'just a laugh'. We shouldn't have to say they are just doing their job & trying to keep you safe. But sadly we do.
"Last night, firefighters had bricks thrown at them as they dealt with wheelie bins that had been set alight in Mersey Park, Tranmere Thankfully no one was injured but that doesn't make this behaviour acceptable.
"Fire engines carry CCTV & footage will be passed to @MerseyPolice.
"Our firefighters are mums & dads, aunties & uncles, brothers & sisters & friends of members of the community.
"An attack on us is an attack on your own community. Respect your community. Respect the emergency services. Respect yourself."
The warning comes as both Merseyside Police and Merseyside Fire and Rescue Service are encouraging everyone to play their part in keeping communities safe over the Halloween and Bonfire Night period.
Eight fire officers were attacked over last year's Bonfire Night period when they were attending incidents across the region.
Merseyside Police Chief Inspector Peter Clark told the ECHO earlier this week that the attacks "make no sense."
He said: "It's deplorable behaviour when people intend to attack our emergency service workers.
"We work closely with the Fire Service and with North West Ambulance Service to try and protect them the best we can.
"We usually coordinate our responses, so we will send police officers along with the fire service officers to protect them while they do their job."
Merseyside Fire and Rescue Service Group Manager Paul Kay also told the ECHO : "What this means is that potentially we have a fire engine and staff unable to attend more serious incidents where life or property is in danger.
"We'd always urge members of the public that these people riding in the fire engines and driving police cars are members of our community and [are here] to help us, help you, to keep our community safe."
