"The search is on at present in her office and when it ends, we will inform details about it," CBI sources said.
On Monday, investigators found a pendant from the activist's car and also came to know that calls were made/received from her mobile even after her death, sources said.
However, a senior police official said that since they have handed over the entire case to the CBI for probe, he would be able to share any details.
He said that normally a mobile phone takes 48 hours to clone and during that period if somebody had called on that number or SMS-ed then definitely it will come on record.
Earlier, the police had also recovered a gold chain from her body and possibly this particular pendant may be the part of it, sources said. Shehla was shot dead on August 16 outside her house here.
