Lucknow, Aug 8 - As part of the probe into the arson attack on Uttar Pradesh Congress chief Rita Bahuguna Joshi's house, the Crime Branch-Criminal Investigation Department (CB-CID) will collect call details of several senior policemen, officials here said Saturday.

'By analysing the call records we will be able to assess the locations of the policemen at the time of the arson incident,' a senior CB-CID official told IANS on condition of anonymity.

The CB-CID's decision to collect the call records comes in the wake of charges made by Joshi and her party that Chief Minister Mayawati had orchestrated the attack and acting on her directions several police officials present in close vicinity of the house had not attempted to control the mob that resorted to arson last month.

'In the presence of policemen, arson and vandalism took place at Ritaji's residence. During the entire incident, cops remained mute spectators.
