Three charged over Sydney man's kidnapping

Three men have been charged after a 31-year-old man was kidnapped and bashed at a western Sydney home.

Police say they were called to an address at Cranebrook about 11pm on Monday.

When they arrived, three men tried to flee the property on foot but were tracked by the Pol Air helicopter and arrested.

Inside the home, officers found the injured man who has a suspected broken jaw and numerous cuts and bruises.

Police say he was held and assaulted for several hours but his injuries are not considered life-threatening.

Three men aged 36, 46 and 59 were taken to Penrith Police Station and charged with kidnapping and assault.

They were refused bail to appear at Penrith Local Court on Tuesday.
