The cause of a basement fire under the Asylum club on Main Street is still under investigation, Ansonia Fire Marshal Ray Tingley said.
“The cause of the fire will remain open and undetermined at this time,” Tingley said in an e‑mail Monday. “An intentionally set fire has been ruled out. The fire started in the basement and had begun to move up an interior wall into the ground floor where it was stopped.”
There were no injuries reported during the blaze, which was reported about 4 a.m. Monday.
