West Yorkshire Police are investigating four break-ins which took place between 3am and 5.15am yesterday (March 14) in the Kirkstall area.
All the incidents saw suspects smash windows to enter the building but leave without taking anything.
Detective Inspector Neil Thompson, of Leeds District Crime Team, said: “These burglaries have all occurred in the same general area and over a similar time period and we are looking at whether they are linked.
“We would like to hear from anyone who saw anything suspicious at any of these locations around the time of the incidents.”
In the first incident, burglars smashed an office window at Queenswood Education Centre, in Foxcroft Close, shortly after 3am.
