The most recent victim was 10-year-old Faheem. The boy was taken away by the leopard while playing cricket with his friends.
Wildlife officials said the leopard was killed following complaints of frequent sightings and attacks on people in the area.
"The team was fully equipped with tranquilising guns, cages, nets and with sharp shooters. The man-eater was eliminated in Bomi-Dager (Handwara) after intensive combing and search operations conducted by the wildlife staff," said wildlife warden Rouf Zargar.
Earlier this week, a bear was shot dead by wildlife authorities in the Sopore area of this north Kashmir district, after it attacked and injured a 62-year-old Habibullah in the apple town of Sopore. Another bear was shot dead on November 3 in Bandipora, north Kashmir.
The wildlife department is also searching for two bears, which attacked people and animals in the area.
