In the early hours of Tuesday morning, masked men tried to burgle a store in Colton before targeting another store in Leeds city centre.
Both attempts were unsuccessful and the suspects left empty handed.
Police were first called to a break-in at the Sainsbury's store on Stile Hill Way, in Colton, at 1:15am today (Tuesday, August 27).
The suspects, who were driving a white Audi TT, used a sledgehammer to smash through the front door shutter.
They got into the building and attempted to open the cigarette cabinet, but left empty handed after the shop's alarm and smoke screen system were triggered.
Just minutes later at 1:39am, police received another report of a break-in at Sainsbury's in Wellington Place in Leeds city centre.
The same suspects in a white Audi TT had attacked the front shutter of the shop with tools, but again they left empty handed.
The men fled the scene after security staff from a nearby building were alerted to the crime.
