A spokeswoman for Premier Daniel Andrews said on Sunday it was “a matter for the Labor Party” and did not provide any more comment.
When asked if Ms Vaghela or Ms Connelly wished to comment, the spokeswoman said: “No they don’t.”
Tensions are flaring within state Labor as Left and Right faction jostle for control of key seats in Melbourne’s west and south-east ahead of preselections.
Mr Sidhu has become a controversial figure within the party since he lost pre-selection for the seat of Tarneit to Ms Connelly in 2017 and crossed from the Right faction to Mr Andrews’ Socialist Left faction.
He publicly decried factionalism within the party following his loss, however, has been the target of claims of his own branch stacking, especially within the western suburbs’ Indian community.
Several witnesses told The Age the conversation quickly became heated and Mr Sidhu asked a group of attendees to leave.
The meeting at my house was scheduled but did not happen due to unacceptable behaviour and I am referring a complaint to the police to investigate.
On video seen by The Age, Ms Vaghela and Ms Connelly attempt to obscure their faces as people are forced out of the suburban home where a meeting continued on the front lawn.
Both MPs are aligned to Mr Somyurek, a powerful Right faction figure within the Victorian ALP, who is a senior member of the Andrews government.
Mr Sidhu can be heard telling people to leave his parents’ back garden before he is struck in the head by an unknown man.
One version of the video shows some people smiling and laughing after Mr Sidhu is struck.
“The meeting at my house was scheduled but did not happen due to unacceptable behaviour and I am referring a complaint to the police to investigate,” Mr Sidhu said.
“At this stage as I have asked the police to investigate I have no further comment.”
One source present said some of the Indian community became upset that Muslims had arrived and began demanding they leave.
Another said Mr Sidhu had angered branch members, who had been caught offguard by a “surprise” meeting at his home.
Victoria Police confirmed officers were called to Babele Road property about 11.30am following reports of an assault.
“No one required medical treatment,” a spokeswoman said. “Police are investigating the circumstance surrounding the incident.”
A Victorian Labor spokesman said the party had received “no notification or complaints from branch members about this matter”.
“Any referrals to other organisations are matters for them,” the spokesman said.
