Pune, Feb 15 (IANS) Four teams of the state's Anti-Terrorist Squad (ATS) have been formed to probe Saturday's blast at an eatery here that killed nine people, city police chief Satyapal Singh said here Monday, adding the probe 'is proceeding in the right direction'.

'So far, we have not yet got any concrete leads on the perpetrators of the incident. We are investigating from all angles and we don't rule out anything,' Police Commissioner Singh said at a press conference here.

It is not yet clear which group or organisation was responsible for carrying out the bombing at the German Bakery, that also left 60 people injured.

To a question, Singh said the report of the forensic sciences lab, which could confirm the composition of the bomb, has not been received yet.

'It was expected today but has not been received. It may come tomorrow or maybe the day after,' Singh said.

Referring to the victims, the police chief said the bodies of all the victims have been handed over to their family members after completing the relevant formalities.

'The condition of three of the injured continues to be serious and of concern,' he added.

Stressing that the police were doing their best, Singh requested the public to come forward with any kind of information that could help the investigators 'in the interest of the city and the nation'.
