"They were looking for Antony's son, who worked as Andrews' assistant as there were some issues between them. But when they couldn't find the son, they thrashed Antony and others. We have asked Behra to speed up the probe into the matter," said Kumar.
Andrews, 44, shot to fame after the release of his first film as a full-time director in 2005. The film, "Udayananu Tharam" starring superstar Mohanlal, went on to become one of the biggest hits in the history of Malayalam cinema.
Since then Andrews has emerged as one of the most sought after directors in the Malayalam film industry.
"We have also told the producers associated with Andrews to be careful," Kumar said.
Andrews has also filed a complaint with the police, alleging that it was he who was roughed up by Antony and his friend.
