Prosecutors in Barnstable say 56-year-old Edward Kulik Jr. of Centerville sexually assaulted a teenager. The incidents allegedly took place in 2010 and 2012.

A spokesman for the department says, “These disturbing, serious allegations warrant our full attention and the Boston Fire Department will monitor and take swift appropriate action if and when it’s necessary.”
