The 75-year-old woman was punched in the head and verbally abused after her dog approached a man with a poodle in a park on Leila Rd in Carnegie on Tuesday June 23.

The man asked her if her dog was registered and attacked her as she put her animal back on its leash.

A good Samaritan stepped in and stopped the man, but he continued to yell abuse while she walked home.

The offender is believed to be aged in his 60s, of southern European appearance, about 157cm tall and was carrying a red or orange bag.

Anyone with information is urged to contact Crime Stoppers on 1800 333 000
