"A team of three officers of UP ATS was rushed to Mumbai immediately after the attack and we are closely coordinating with the Maharashtra police," Special Director General of Police Brij Lal told reporters.
"Though no specific clue has come up so far, but we are looking into all aspects that what links UP may have with Mumbai blasts," Brij Lal said.
Though it was not confirmed by senior officers, but some suspected militants of IM and other organisations lodged in UP jails have been quizzed.
A team of Maharashtra ATS also visited several places in UP in the last two days looking for clues, sources said.
