A desperate search is continuing for a 75-year-old man living with dementia, after a suspected sighting of him more than three weeks after disappearing from Sydney’s southwest.

Ivan Jakus, who is also known as John, was last seen at a club on Cowpasture Rd in Leppington about 5.30pm on April 21.

The elderly man was reported missing after he failed to return to his aged care facility in Casula.

Inquiries from police revealed the elderly man was seen leaving Leppington Railway Station about 7.30pm Sunday night, and was later seen outside a home on Ramsay Rd in Rossmore about 10pm.

“Police and family have serious concerns for Ivan’s welfare as he lives with dementia, requires regular medication and has been missing for several weeks,” a police statement read.

A multi-agency search involving police, SES and the NSW Rural Fire Service were deployed across the Rossmore area in hopes of finding the man.

On Saturday May 2 about 11.30am, police received dashcam footage of an elderly man struggling on the median strip of Elizabeth Drive, about 750m southeast of the M7 Motorway in Cecil Hills.

While police were unable to locate the man at the median strip, they believe it may have been Ivan.

He has been described as being of caucasian appearance, about 165cm tall, of medium build and with short grey hair.

He was last seen wearing a white Adidas tshirt, dark navy shorts, white socks and a pair of dark-coloured shoes.

Police believe Ivan is still travelling on foot around the Leppington area.

However, because Ivan is “extremely mobile”, they said he may have travelled further.

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