Acclaimed music director Ismail Darbar was arrested in connection with an assault case and later secured bail from a Mumbai court, police said Wednesday. Darbar's son Zaid was also arrested for allegedly assaulting an assistant director over a monetary dispute and is now out on bail.

Darbar's arrest came a day after his son Zaid and two friends - Mohsin Khan and Nishant Singh - were arrested in the same case involving an assault on an assistant director, Prashant Choudhary, in suburban Oshiwara late Monday.

Assistant Commissioner of Police S.R. Dhandhar said the arrests followed a complaint lodged by Choudhary Tuesday over a dispute relating to some pending payments.

According to the complainant, Choudhary (30) was accosted by Zaid, Khan and Singh late Monday in the parking lot of their apartment and a heated argument ensued over the pending payments due to Choudhary.

The trio attacked Choudhary with hockey sticks and later Ismail Darbar also joined them in assaulting him.

He later lodged a police complaint after which the father-son Darbar duo and Khan and Singh were arrested and released on bail.
