New Canaan police are looking for three suspicious men who seemed to have attempted a burglary after sealing a resident's driveway Tuesday afternoon on Old Stamford Road.

The victim, an 86-year-old man, told police the three men arrived at the residence unannounced at about 11:45 a.m. and offered to do the first coating for free and only charge for additional coats. The homeowner agreed and the men started sealing his driveway, police said.

The victim told police he thought it was odd that one of the men was wearing sneakers while doing such work, but he did not suspect anything was wrong.

About 45 minutes later, one of the men went inside the house to negotiate the price with the homeowner, police said. The men asked for $800, but the victim thought it was too high so they dropped it to $200, according to the report.

The homeowner then asked the men to wait outside so he could get the money and when he went back to the driveway, only one man was there, police said. While the victim was paying, he noticed the suspect was purposefully trying to distract him, according to the report.

At that point, police said, the homeowner walked back into the house and found the other two men standing in his living room, police said. The victim immediately called 9-1-1 and the two men ran from the residence to their vehicle, according to the report.

The suspects are described as black males, approximately 5 feet 8 inches to 5 feet 10 inches tall. Police said they were driving a black pickup truck with a black cab over the bed and white lettering on the driver's door, which read "A & B." The resident was not able to see the marker number because a piece of cloth was obstructing the plate, police said.

Sgt. Carol Ogrinc said nothing was missing from the residence but police believe the men could have been attempting to steal items.

She asked residents not to accept unsolicited work offers and to look for references and check licenses when hiring contractors.
