Jammu and Kashmir Director General of Police Dilbag Singh said on Wednesday he was hopeful that the summer this year in the Valley will be peaceful.
"We are hopeful that the situation will remain peaceful," he told reporters in Srinagar.
Mr Singh was responding to a question about any possibility of disturbance during the summer in Kashmir.
He referred to successful anti-militancy operations in January in the valley and Jammu.
"We have busted several modules of terrorists last month but the grenade attack at Lal Chowk shows that there are some remnants. But the security forces are alert and foiling their plans," the police chief said.
He said police has got some clues about those who carried out the grenade attack at Lal Chowk on Sunday "and we will soon get to him".
Terrorists hurled a grenade on Central Reserve Police Force (CRPF) personnel posted on duty near Pratap Park in busy Lal Chowk area of the city on Sunday, injuring two soldiers and seven civilians.
