"As part of this, we have been conducting searches in Aldershot, around the area of the station, and this will continue.
"I want to appeal again for anyone with information about Kiran and his disappearance, however small it may seem to you, to get in touch with us."
Kiran has links to Aldershot, Farnborough, Basingstoke and Andover.
