Police have a man in custody believed to be involved in a suspicious fire this afternoon on Talbot Hill Road South.

Police Tuesday morning served a temporary protection order to a resident of a house in the 1500 block earlier today and returned in the afternoon to make sure the man had left.

On arrival police saw a man run from the scene and then saw smoke coming from the back of the house and reported it on fire.

Firefighters arrived on the scene to find the home “heavily involved” and set up a defensive attack on the blaze, due to the possibility of ammunition being inside the house, said Deputy Fire Chief Greg Hartman.

Hartman said firefighters battled the fire for more than an hour. He said they heard some pops and bangs from inside, but no explosions.

No injuries were reported.

The suspect, a 45-year-old man, is in custody and being questioned. The man will be booked for felony investigation of arson.
