UP DGP OP Singh told reporters, "Those who have murdered Tiwari are said to be his acquaintances. They spent over half an hour with him and even gave Tiwari a box of sweets and after it the murder took place. We have got some vital clues and based on CCTV footage and other evidence, we are working on the case."
He said teams had been formed to crack the case.
"We have also got some call details. The special task force has been engaged in the case," he said, adding that it was "purely a criminal activity" done by two people.
The UP DGP said there were "some minor law and order problem" in the area after the murder took place with local people saying that such incidents should not take place.
"But, the situation now is under control. Police officers are patrolling the area. In the next 48 hours, we will catch the culprits," he said.
When asked whether there was any possible terror angle in the incident, Additional Director General of Police (Law and Order) PV Ramasastry told media, "All the angles are being looked into. And, it would be improper to jump to any conclusion."
Senior Superintendent of Police Kalanidhi Naithani said prima facie it seemed to be a case of personal enmity.
He added that teams had been formed to crack the case.
