Accused kidnapper arrested after bar fight

A man accused of the attempted kidnapping of a woman in Sydney's inner west a week ago allegedly assaulted three men at the weekend, according to court documents.

Dean McGlinchey didn't appear when his matter was heard at the Parramatta Local Court on Monday.

The 27-year-old was arrested on Sunday alongside a 57-year-old man after a series of assaults on Sydney's northern beaches.

Police allege McGlinchey assaulted two men in Terrey Hills at about 1pm before hitting another man across the face with a bar stool in Dee Why, knocking him unconscious.

The 54-year-old victim underwent surgery at Royal North Shore Hospital for a serious facial laceration and a missing front tooth, police said.

McGlinchey, who did not apply for bail, is expected to appear before Central Local Court on Thursday.

He faces six charges, including attempted kidnapping, affray, assault and low-range drink driving.

McGlinchey was previously charged with the attempted kidnapping of a Taiwanese national in Burwood on June 4.

McGlinchey's lawyer requested medical treatment for her client but did not specify what for.

The 57-year-old man was granted strict conditional bail to appear before Manly Local Court on June 21.
