Director General of Police OP Singh said on Thursday six men from Baghpat and Saharanpur districts have complained that they were told to take part in stone-throwing.
Fed up with this, they returned home, the officer added.
The men had gone to Pulwama to work as tailors at a monthly salary of Rs 20,000.
"We will deal with this issue very discreetly," the DGP said. The state's anti-terror squad will probe the matter.
He said a man, identified as Nasim, told police that he and some others were kept at a factory in Pulwama.
On one occasion, the labourers there took part in stone-throwing.
He was also asked to throw stones but he refused and escaped from the place, the police added.
