The wife of Liberal MP Brad Battin was left in tears after being pushed and shoved at Thursday night's heated anti-East West Link protest.

The violent protests angered the parliamentary secretary after his wife, Jo, was pushed as they entered the fundraiser in the CBD on Thursday night.

Mr Battin said he and his wife were separated by the protesters as they entered the event at the Regent Plaza Ballroom in Collins Street, with his wife pushed into a corner.

He said his wife was in tears after the incident and was now being trolled on social media.

Three people have been arrested for allegedly attacking police during the rowdy, aggressive protest outside the Liberal Party election fundraising event.
