The Boston Police Department reports it is investigating a string of housebreaks from Ashmont to the Southeast Expressway between Friday and Sunday.

In all cases, the thieves got nothing, either because they were confronted by homeowners or because they broke into empty units, police say.

The first break was reported at 9:20 p.m. in a vacant first-floor unit on Boutwell Street, followed about 90 minutes later by an attempted housebreak on Lombard Street:

Victim says he was home at the time of the break and was able to scare the suspect off.

The next break was reported shortly after 3 a.m. on Saturday on Tolman Street:

Victim says she awoke to her dog barking. Upon further investigation, she discovered that her rear porch door had been unlocked and various pieces of lawn equipment, which had been stored under the porch, had been strewn about the yard. Victim says it appears nothing was stolen.

This was followed by a break around 11 a.m. on Magdala Street, again with nothing taken, and finally, one around 2 a.m. today on Mather Street:

On arrival, officers spoke with victim who stated that she was asleep when she heard a noise in her residence. When she went to investigate the noise, the victim states she observed and confronted two black teenagers who fled upon seeing her.
