BABYLON, N.Y. (CBSNewYork) — Police on Long Island received multiple calls Tuesday evening about a loud noise of unclear origins.

Suffolk County police said the calls about the noise in Babylon, Lindenhurst and West Islip began coming in around 6:10 p.m. The incident was still investigation late Tuesday, but police confirmed there was not an explosion.

Back in January, a loud noise and rumbling that people felt across South Jersey and Long Island turned out to be a sonic boom.

The Pentagon confirmed the sonic booms were from F-35’s out of Maryland in that case.
