Two men have been charged after they allegedly bashed and robbed a 60-year-old man at a park in Sydney's southwest.
Neville Shaw was set upon by four men at Koshigaya Park in Campbelltown about 8pm Friday on his birthday.
The grandfather, who devotes his time to the organisation Lifeline, was helped by passers-by and taken to Campbelltown Hospital.
He was out with his family for a special dinner when, around 8pm, a group of thugs spotted him and attacked him.
'I cut through Koshigaya Park to Woolworths and then that was it, just a blank after that,' Mr Shaw told the Seven Network on Saturday.
The thieves escaped with more than $300, some of which was given to him as a gift and some which was set aside for bills.
'Money's not everything but it makes the world go round, you've got to work hard for it nowadays and that's it,' he told 9 News.
'It's totally unacceptable. In this day and age people should be able to get on with people and leave other people alone,' Inspector George Psaroudis said.
Police have arrested two men, 19 and 20, who appeared in Parramatta Local Court on Saturday charged with aggravated robbery, and are searching for two others.
