A Transit Police officer may very well have saved the life of a pit bull terrier that was wandering along the commuter rail tracks in Dorchester Monday morning.
A concerned citizen spotted the dog, later named Rudolph, around 10 a.m. as he roamed between Savin Hill and JFK-UMass Stations.
Upon receiving the call, Transit Police Officer Lisa Murawski-Dupont bicycled the entire distance between stations, eventually locating the dog.
Commuter rail service was temporarily suspended as Murawski-Dupont coaxed the dog from the tracks.
Transit Police said in a statement that "Rudolph had a very friendly disposition and made fast friends with Officer Murawski-Dupont, whose actions probably saved his life."
Rudolph, who police said was named "after Santa's #1 helper," was brought in by the Animal Rescue League of Boston. Officials are urging anyone with information about the dog to call the Transit Police Special Crimes Unit at 617-222-1170 or the animal league directly at 617-426-9170.
