The Andhra Pradesh police has released sketches of a bicycle used in the twin bomb blasts in Dilsukhnagar here last month which killed 17 and had injured more than 100 people.
Cyberabad Police Commissioner Dwaraka Tirumala Rao released the sketches of a damaged bicycle here tonight.
Since the rear portion of the bicycle is totally damaged and only its front portion is available, it can be concluded that the explosive charge had been fixed on the bicycle's carriage, Rao said.
The bicycle's damaged parts found in front of the Anand Tiffin Centre at Konark Theatre revealed that it was assembled with parts of bicycles manufactured by different companies, he said.
The bicycle's main frame, handle bar, bumpers and fork belong to Atlas company, while the front rim was manufactured by Usha, he said.
Giving further details of the bicycle, he said that the front tyre was manufactured by a company called Ganga in April last year, while its front tube is Gamra (Ganga) which was manufactured in October last year.
The bicycle's chain was a heavy duty 'KW', made in England. It was learnt that this product was available in the market three years ago, but became unavailable later, due to its high cost, Rao said.
It was presumed that offenders behind the blasts might have taken shelter in rented houses for about one or two months before the blast of February 21, he said.
A thorough examination revealed that the bicycle's upper and bottom fork cups were replaced recently with 'BM' make cups and these were not fixed properly, probably due to lack of expertise, he said.
