A woman was seriously bitten by an alligator on Saturday in a Florida river, according to fire officials.

MyFoxOrlando.com reports the 37-year-old woman was bitten in the torso and suffered a lower arm amputation below the elbow, according to Seminole County Fire Rescue officials.

Florida Fish and Wildlife officials say the woman was swimming by herself in a busy area in the Wekiva River and decided she wanted to go to a more remote area. Officials tell the Fox affiliate that she felt something grab her arm and pull her under water.

The woman felt her arm break and lost track of how many times the reptile pulled her under water.

Alligator trappers were summoned to the area to try to catch the alligator.

The station reports the woman was taken to Orlando Regional Medical Center.
