Avon police are investigating a home invasion at a single-family home on Jackson Road on Tuesday night.
Police received a 911 call at 7:40 p.m. reporting an armed residential robbery.
Three people were in the house when two males wearing all black and masks forced their way in, ordered everyone to the ground at gunpoint and demanded money, police said.
The residents complied and the suspects ran. Police did not find the intruders.
One resident suffered a minor asthma attack, but did not require hospitalization, police said. No other injuries were reported.
Anyone with information about the home invasion is asked to contact the Avon Detective Unit at (860) 409-4200.
