Police yesterday collected voice sample of Bollywood star Aishwarya Rai and also recorded her statement to find out authenticity of the audio tape in which actor Salman Khan flaunted his alleged underworld links while purportedly conversing with the actress.

A Crime Branch team reached Aishwarya's house in suburban Bandra this morning and recorded her statement, while experts recorded a voice sample, sources close to Rai said.

Salman was yesterday summoned to the Crime Branch office in Andheri, where his statement and voice sample was also recorded.

Although sources close to the actress said that the police team had recorded her statement and taken voice sample, DCP Dhananjay Kamalakar of Mumbai crime branch denied that there was any such move.

"We have not recorded her statement or taken voice sample," he told.

However, Police Commissioner, A N Roy told that the police would take her voice sample and record Rai's statement during the day.

The audio tape, released by television channels and whose transcripts were published by a newspaper, claims voices of those of Salman and Aishwarya conversing with each other.

In the tape, Khan not only flaunts his connection with the underworld, but also threatens that the underworld figures would "eliminate" Rai and her family if he so desired.
