The husband of well-known filmstar of yesteryears, Nutan, was allegedly killed in a fire that broke out on the 31st storey of a building in Colaba in south Mumbai, police said on Wednesday.

The body of Rajneesh Behl, father of actor Mohnish Behl, was found in a badly charred condition, almost four hours after the fire broke out on the top-floor of '-Sangeet' building late last night, police said here.

Although the fire brigade personnel had asked the residents of the building to evacuate it, they did not realise that Behl was inside the top-floor flat in which the fire had erupted.

His son Mohnish was also away on a shooting and arrived later in the night, police said, adding the existence of the body came into light with the fire fighting operation concluding at around 4am.

Over ten fire tenders and high speed elevators were pressed into service to contain the fire while power supply was disconnected, fire brigade sources said, adding the cause of the fire was yet to be ascertained.

The body has been sent for post-mortem, police added.
