Denton police are asking for help in identifying a thief who is gaining entrance into at least one business by posing as a fire extinguisher repairman.
Police said the man tried to get into two businesses by asking to see the fire extinguisher and succeeded at a medical building, where he stole a wallet. But he left Beaus Bath House and Doggie Spa when employees got suspicious and questioned him.
The man also stole two iPads from a hotel room after using a different tactic, police said.
"We know what he is doing, and we need to get him off of the streets," Denton police spokesman Ryan Grelle said.
Rockwall police are seeking Paul Roberts, who has used the same tactics in that city, but Denton police are not connecting their thefts to Rockwall. Rockwall police say they are worried Roberts could be violent.
Before letting anyone into a home or business, ask for their ID, police say.
