LAKE WORTH, Fla. (AP) — Authorities say a 91-year-old South Florida man jumped out of bed naked and held an intruder at gunpoint until deputies arrived.

The Palm Beach County Sheriff’s Office said Robert E. Thompson woke up Saturday morning after a would-be burglar climbed his backyard fence and was met by his charging dog, Rettt, a Rottweiler and Doberman pinscher mix. Thompson heard the commotion, grabbed his .38-caliber revolver and phoned police without ever getting dressed.

Deputies say Thompson fired a warning shot as 26-year-old Jose Pasqual started to come toward him. Thompson kept his gun trained on Pasqual until deputies arrived.

Pasqual was booked in the Palm Beach County Jail on a burglary charge and did not immediately have an attorney.
