According to SSP Preetinder Singh, the incident occurred last night when 250-year-old Lal Mandir was targeted by the robbers.
He said the stolen idols were worth crores of rupees, adding that a hunt was launched to nab the culprits.
Local BJP leaders, along with villagers, staged a protest on the Agra-Aligarh road demanding prompt action in the case.
The priest, who had put up a resistance, was hacked to death with an axe by the robbers, the SSP said.
