Roselle Police are pulling a Tom "I can't carry a gun" Dart

Police in west suburban Roselle have launched an investigation into the death of a dog that was tasered last week after it bit and severely injured a 55-year-old woman inside her home, authorities said.

The attack that sent the woman into emergency surgery occurred just after 9 p.m. on May 8, but was only revealed by Roselle police in a news release on Monday.

Authorities said the American Staffordshire Terrier -- whom officers were familiar with because of a previous bite incident -- was tasered and put it in a holding cage after previous attempts to detain the animal using only a catch pole weren't successful.

The dog was taken to a local area hospital, where it later died.

Officers went to the home in the 500 block of Rodenburg Road for receiving a call of a woman being bitten by a dog.

Inside, police found the woman with severe bite wound to her left leg, police said. Authorities helped the woman to a waiting ambulance, that took her to Alexian Brothers Medical Center in Elk Grove Village, authorities said. Her most recent condition wasn't immediately known.

Officers later found the woman's husband inside the kitchen, using a broom to hold the dog at bay, police said.
