Unidentified persons entered the St Thomas Catholic Church at Taherpur late last night in an attempt to steal valuables, Nadia Superintendent of Police (SP) Bharatlal Meena said.
Nadia district magistrate Vijay Bharati has confirmed the incident.
The Church's caretaker this morning found that the main door, which he had locked last evening, was ajar and a few belongings and the cyborium were broken and thrown outside, the police said.
"Though all the valuables of the Church are intact, we are trying to find out how they managed entering the Church despite the main door and windows were locked from inside," a senior police officer of Taherpur Police Station told PTI.

Father Satish Makal said that the ciborium and the tabernacle were thrown outside the church building.
During the initial probe the police found that nobody in the Church's densely-populated neighbourhood "heard anything suspicious" last night.
The police had questioned two priests and a couple of medical officers staying at an adjacent building.
Taherpur's St Thomas Catholic Church is around 25 km away from the Ranaghat Church where a septuagenarian nun was allegedly raped by seven persons after a robbery there in March.
