Major police operation underway at popular Sydney spot

A major police operation and search is underway after a man jumped into the Nepean river south of Penrith and failed to resurface.

Emergency services were called to Nortons Basin at Mulgoa on Saturday morning after a man, who had been fishing, told his partner that he was going for a swim, NSW Police said.

After diving in he failed to resurface, prompting the woman to raise the alarm.

The man is believed to be in his 60s.

“A search operation is now underway involving officers from Nepean Police Area Command, specialist members of State Emergency Services’ swift-water rescue team, Fire and Rescue NSW and NSW Ambulance,” NSW Police said in a statement.

A police helicopter is also en route to help with the search.

More to come.
