Rapid Action Force personnel on Tuesday conducted a flag march in this textile town, hit by four bomb blasts on Friday, to "dispel the fear factor" among people, a senior police official said.
"They (flag marches) are just being done to dispel the fear among locals. The RAF is also getting familiarised with the local area," Nashik's Superintendent of Police Rajvardhan told reporters here.
Police are questioning 40 to 50 people in connection with the bomb attacks that killed 31 and injured nearly 300, and teams of investigators have fanned out to various places, he said.
"We are also checking all out-station calls made from Nashik and Malegaon on that day," he said.
Rajvardhan said police have also got leads from outside Malegaon. Reports from two forensic laboratories on samples collected from the blast sites in the town are expected in 48 hours, he said.
A report received on Monday has said that the bombs used in Malegaon contained RDX.
