Billings police reported a rash of break-ins in the Heights last week.
Sgt. John Bedford said stereos, wallets and cell phones have been among the items stolen. The target area was around Nutter Boulevard, Constitution Avenue, Babcock Boulevard and Gov-ernor's Boulevard.
Police also recently recovered a batch of sports equipment, apparently stolen from a Heights Little League organization, he said.
Part of the increase in crime is that summer has arrived and everyone is more active and out and about later. That includes people who are nearby outside but leave their houses unlocked and those who are looking for places to make mischief.
Bedford said residents can help protect themselves by locking their vehicles and houses.
He encouraged residents to report suspicious activity, especially people who are checking doors and prowling around neighborhoods.
"Several people (victims and neighbors) have said they had their windows open and heard something but didn't report it at the time," Bedford said.
