Retail thieves struck at the Penn Valley Acme twice in two days last week, Lower Merion police said Monday.

About 10:30 a.m. Thursday, July 19, two men filled a shopping cart with more than $400 worth of baby formula, pushed it out of the store without paying and were not seen again, police said.

The next day, about 10:55 a.m. Friday, July 20, a 31-year-old Philadelphai man stole $404 in Duracell batteries from the grocery store, then ran east on Montgomery Avenue toward the Rite Aid pharmacy a quarter-mile away, police said.

The man was apprehended, and after an Acme employee identified him, he was charged with retail theft and receiving stolen property, both misdemeanors.
