Two teenagers who bashed and robbed an elderly resident during a violent home invasion at a Tuggeranong retirement village tried to steal the man's car to escape, police say.
The two teens are believed to have broken into the man's home at the Goodwin Retirement Village in Monash about 1am on Tuesday, striking him in the head and arm before stealing cash.
The juvenile offenders then tried to flee in the man's car but could not get it started. They smashed a window before they escaped.
The elderly man was treated by paramedics before he was taken to Canberra Hospital with non-life threatening injuries.
A police investigation has been launched and forensic officers have examined the scene.
The offenders are described as about 15 or 16 years of age. One was wearing grey-coloured clothing, while the other was wearing black clothing. Both had their faces covered.
Police have urged anyone with information about the offenders to contact Crime Stoppers on 1800 333 000 or at https://act.crimestoppers.com.au.
