An elderly female was pushed to the ground during a violent home invasion robbery in Strathroy Thursday night.

Strathroy police say it happened just after 10 p.m. on Thomas Street.

They say an elderly couple answered the door and a man brandishing a weapon pushed his way in. The man demanded money and left with an undisclosed amount.

Police say the couple was not injured during the invasion.

London police responded with a K-9 unit but were unable to track the suspect.

He is described as white, in his 20s, about 5-foot-10 to 5-foot 11 with a thin build. He was wearing a dark-coloured hoodie and may have been wearing a hat.

Anyone with information is asked to call 519-245-1250 or Crime Stoppers.
