The Rockland, MA fire department is reporting that part of a lower level ceiling at Holy Family Church collapsed on Thursday morning.

A 20-by-20 foot section of plaster fell, Deputy Chief Bill Ferguson said. There were four workers inside the church, doing demolition of a section of ceiling in the lower sanctuary. The lower sanctuary has been closed for several days while the demolition work was taking place.

One worker was taken by helicopter to a Beth Israel Hospital in Boston. Ferguson said the worker sustained back injuries. The three other workers were not taken to the hospital.

The collapse occurred shortly after 11:30 a.m. Thursday. The church is not releasing a statement and referred questions to the Archdiocese of Boston.
Police and firefighters were still at the scene at 12:48 Thursday. The town building inspector and a structural engineer are being called to the church to determine whether the building is safe.
