Circuit timer was used to detonate the bomb with Ammonium Nitrate 
emulsifier (slurry) stuffed in an Aluminium container. Forensic experts of State police 
unraveled the bomb signature and confirmed that these kinds of bombs are used Indian 
Mujahideen terror modules in Mumbai and Delhi blasts earlier. A preliminary forensic 
report was given to the Investigating agencies. The forensic doctors of OGH mortuary who 
conducted post mortem examination found nails, nuts and bolts inside the bodies. The bomb 
making is pointing finger at IM officials said.
To cause maximum damage the terrorists used nuts, bolts and nails in the explosive 
material which acted as missiles/sharpnels. Investigators ruled out the use of RDX.
An investigating official said ,”the circuit timer is based on delayed mechanism on 
circuit board which detonates the bomb at the time as required. Slurry explosive weighing 
around one Kilogram(from 700 to 1000grams) was used in the second bomb near Konark theater to have maximum 
impact. In the first bomb less amount of explosive material was used.  A 3.9 volt 
battery was used as power source. A detonator wire was also found. After assembling the 
bomb in an aluminium container it was wrapped in a cloth and placed in a bag. Then the 
bag was hung to a bicycle. Same kind of bomb signature was found at two places,” National 
Security Guard Post Blast Investigation Team also found a timer at the scene of the 
offence sources said.  The bombs are placed at a distance of 150 metres.
As there is no live bomb found in twin blasts unlike previous cases it was a tough task 
for the bomb expert to determine the parts ad mechanism in the Improvised Explosive 
Devices used by the terror suspects. The flames that were found after the blasts are due 
to the fuel in vehicles.
Clues teams of city police lead by Dr Gopinath and Prakash found 15 vital clues including 
the melted Aluminium pieces, cells used in calculator, battery, nails, and nuts and bolts 
at the scene of the offence.
Osmania Medical College forensic department head Dr P Hari krishna said  "We retrieved 
nails, nuts and bolts and metal pieces from the bodies that pierced. The bodies are 
mutilated in the abdomen and lower parts(legs) indicating that the bombs were placed at 
lower level. The injuries are similar to that of Gokul Chat blasts. The only difference 
is in Gokul chat there are more injuries on head as the bomb was placed on a height,”
Experts say that difference in bomb making in Gokul Chat in 2007 and Dilshuknagar is that 
wooden containers were used then and now Aluminium were used.
