The terror attack at the Indian Institute of Science had some of the 'trademarks' of Lashkar-e-Taiba, a top police official said on Friday.
"Some of the trademarks are LeT trademarks. But we cannot say this with 100 percent certainty till we have some more definite clues," City Police Commissioner Ajay Kumar Singh said.
Police have not been able to link Wednesday's attack to any groups and are looking at the possibility of drawing sketches of the perpetrators with the help of the injured, he added.
Singh said he had spoken to police in Rajasthan, Jammu and Kashmir, Delhi and Hyderabad, seeking inputs for the investigation of the IISc terror strike but 'they had no intelligence or other information on Bangalore's terrorist attack'.
