The city Detention of Crime Branch (DCB) Saturday filed a chargesheet against 24 undertrial prisoners accused in the 2008 Ahmedabad serial bomb blasts in connection with the Sabarmati jailbreak attempt case.
According to the chargesheet submitted before the metropolitan magistrate B J Ganatra,the accused used books on engineering to make the 213-foot long tunnel. They got the books from the jail library,it said.
The accused used hexa blade,screwdriver,level pipe among others to dig the tunnel. The chargesheet states that while digging the tunnel,the accused used their lungis as rope and milk crates to pull out the soil from the tunnel. To hide the excavated soil,they mixed it with the soil dug for gardening.
The accused used some code words to ditch jail authorities. If jail officers would be seen around the digging site,the accused would utter a word to send alert. The repetition of a word for three times would mean for the accused digging the tunnel to come out. Utterance of four times would mean to shut the digging completely, states the chargesheet.
The entry point of the tunnel was covered by a fence made of blankets so that nobody suspects foul, it further says.
The DCB has shown 169 witnesses,out of them about 20 are convicted prisoner,53 are panch witnesses,while the remaining are the jail officials.
One of the witnesses,Govind Lal Modi,who works as wire-man in the jail,said,Six months back,I had gone to the yard but dont remember if somebody stole instruments from my bag containing screw driver,tester among others. The jail authorities dont maintain a register to keep a record of such instrument.
On February 10 jail officials had reported the finding of a tunnel near barrack number-4 where blast accused are kept.
