Note to aspiring robbers: Don't think the local animal hospital is an easy mark - you never know who their clients might be.

Here's how the Daily News reported a foiled hold up in Philadelphia:

Police said yesterday that an off-duty Philly cop captured a robber seconds after the man held up a Northeast Philadelphia animal hospital last Thursday. Police said Lt. Andrew Napoli was with his dog at the Radball Animal Hospital, on Bustleton Avenue near Tomlinson Road, about 6:15 p.m. when he heard an employee yell, "Help, we are being robbed!"

Napoli, assigned to the Marine Unit, confronted the man and knocked him to the ground. Other officers arrived and arrested David Minarczyk, 46. Police said Minarczyk, of Philmont Avenue, in the Northeast, also robbed a CVS on Bustleton Avenue near Southampton Road three times - on April 25, April 29 and May 20 - and threatened employees with a razor. He was charged with four counts of robbery, aggravated assault, possessing an instrument of crime and related offenses, police said.

In other animal crime news, Chester County veterinarian Tom Stevenson pleaded not guilty to animal cruelty charges in Lancaster County Court yesterday. Prosecutors say Stevenson, who operates Twin Valley Veterinary Clinic in Honeybrook, held a nine-week-old puppy under scalding hot water before performing a tail docking procedure with tin snips without anesthesia. Stevenson's medical license was suspended by the state pending the outcome of the trial, expected some time this fall. For the full story in the Lancaster Intelligencer Journal click here.
