The father of murdered teenager Aarushi Talwar today claimed that his e-mail account which he used for communicating with the CBI has been hacked and fears that the information in it could be "misused".

The Hotmail account of Rajesh Talwar was allegedly hacked a week before the CBI submitted its closure report in the Aarushi Talwar murder case on December 29.

"I was surprised when on the morning of December 23 some of my friends called me up asking me if I needed any help. Mails were sent from my account to my friends telling them that I was in some foreign land and needed help. It was then that I found that my e-mail account was hacked," Talwar told PTI.

He said, "I check my e-mail account on almost daily basis as this is the only account that has been used by us to communicate with the CBI on matters related to Aarushi's murder. I fear it can be misused."

14-year-old Aarushi, the only daughter of dentist couple Rajesh and Nupur Talwar, was found dead in her apartment in Jal Vayu Vihar, Noida on May 16, 2008.

Police had named Hemraj, their domestic help, as the main suspect until his body was also discovered in the same house the next day.

"Everything that they (CBI) wanted to know from us about Aarushi which could be of help in the investigation was communicated to us through email and if we had any queries they would send replies to this account," he said.

The CBI took over investigation into the double murder on June 1, 2008.

However, it has not been able to make any headway in the case and last month filed a closure report in a Ghaziabad court saying it could not get sufficient evidence to nail anyone.
