Salem and Marblehead police officers searched the area of Ocean Avenue early Saturday morning for evidence of what could have caused the large boom that prompted residents across the area to call 911.
According to Sunday morning's Salem police log, At 1:34 a.m., police received multiple calls regarding a "loud bang" on Ocean Avenue. They were unable to locate the source.
Many of our readers in Marblehead also reported hearing the sound, which has some town residents wondering whether or not it is coming from the harbor.
We even received word of the noise on our Salem Patch Facebook page.
