India, July 30 -- The Uttarakhand Police plans to install thermal CCTV cameras and high-mast LED lights, and clear bushes as part of efforts to solve the mystery surrounding a series of stone-throwing incidents in Nainital and strengthen surveillance.

Police superintendent Jagdish Chand, who inspected the affected areas following another stone-throwing incident on Wednesday, directed implementation of the proposed measures at the earliest.

Mysterious stone-throwing incidents have been reported since July 10 in areas such as Zila Panchayat Road, Mevilla Compound, Zila Panchayat Complex, Cement House and Jivji Cottage. Large stones have repeatedly landed on the roofs of houses, injuring at least four people so far and triggering panic.
