A Swedish national, whose cell phone was used by terrorists to speak with their Pakistan handlers, on Wednesday told an anti-terror court here that she had checked into a room at hotel Oberoi Trident on November 26 last year but left it in a huff after she heard a burst of crackers.

Lisa Ringaner (26) said she telephoned the reception to find out what had happened but did not get response after which she decided to leave the room.

"I left behind all my belongings including mobile phone", she told Special Public Prosecutor Ujjwal Nikam.

The witness had came to the court along with her friend.

Lisa further said she did not remember her telephone number as she had obtained a temporary connection from Vodafone.

She was then shown her application form submitted to Vodafone to obtain the connection. Lisa went through the form and read out the number which was allotted to her.

The court took on record her cell phone number and a copy of her passport.
