Also overnight, an intellectually disabled teenager has been flashed in Sydney's southwest and police are looking for an elderly man who went missing on the Far South Coast overnight. During the Balgowlah home invasion at Griffiths St unit, before 9.30pm, two masked men forced their way in, before attacking the 23-year-old sole occupant to his leg and elbow with a machete and spraying him with a substance believed to be pepper spray in his face. The men fled and the victim was treated at Royal North Shore Hospital for cuts to his leg and arm. Police this morning couldn't say if anything had been stolen and they believed it was a targeted attack. The intellectually disabled teenage girl, 17, who was flashed at Minto was walking along Guernsey Ave, when a man her in a car approached her, asking if she wanted a lift at 1.30pm on Friday.
