A series of arson attacks in a part of Leicester have caused substantial damage, police said.
In the past five weeks, four separate incidents - all taking place in the early hours of the morning - have been reported in Glenfield.
Recycling bins, domestic wheelie bins and two skips were set alight.
Appealing for witnesses, officers emphasised that such attacks risked serious injury to residents, as well as damaging property.
The incidents took place between 27 June and 4 August.
Sgt Rachael Payne, from Blaby local policing unit, said all of the incidents happened within a small area.
She said: "Thankfully no one was injured, but the fires caused a substantial amount of damage, as well as considerable concern to members of the community."
"We want to stress to those responsible the potential dangers of starting fires and that if these acts of vandalism continue someone may get seriously injured."
