"Congress candidate Kirit Patel was present when the incident happened," police said.
Meanwhile, Congress workers alleged the camera of the flying squad members was broken because they were recording visuals of women party workers.
"Their camera was broken because they were taking video of lady workers," a party worker said.
When contacted, Patel termed as rubbish the police' claim Congress workers were involved in the attack.
"This is rubbish that Congress men attacked the EC team. I am not contesting the election for the first time. This is my fourth election and not a single complaint has been filed against me," Patel said.
