Detectives from Merseyside Police are appealing for information after a robber stole money from the home of an 88 year-old woman in Litherland.
The man entered the house on Moss Lane at about 9.50pm on Monday 4 July and pushed the pensioner to the floor while demanding cash.
After a brief search of the property he took two £5 notes and fled the scene in the direction of Litherland Moss Primary School.
Witnesses described the male as white, aged 35-40 years, unshaven and wearing a blue beanie-type hat, blue waterproof jacket and blue trousers.
CCTV and forensic opportunities have been undertaken together with house-to-house enquiries in the local area and an investigation is underway.
The pensioner was taken to hospital with suspected broken ribs and was kept in overnight.
Detective Inspector Robbie Moss said: “Offenders like this deliberately target the most vulnerable in our community in their own homes, a place where they have a right to feel safe and secure.
“But I want to reassure the public that Merseyside Police takes the protection of the most vulnerable members of our communities very seriously and we will do everything we can to find the person responsible for this.
“A neighbour initially saw the man we want to speak to on Moss Lane and when they went to check on the pensioner the same male answered the door to the house before fleeing the scene.
“I would appeal to anyone who may have been in the area of Moss Lane and saw a male fitting the description or saw anyone acting suspiciously in the area last night to get in touch.
“I would also appeal to people to keep an eye on any elderly and vulnerable neighbours and family members. If you notice anyone suspicious in the area, always call the Police or contact your local neighbourhood policing team for more advice.”
Anyone with information is asked to Merseyside Police on 0151 777 3835 or the confidential Crimestoppers line on 0800 555 111.
