Investigators are confident that the same man was involved in all the incidents. Although it was not possible to be certain, it appears likely, said Officer Eddy Azcarate, a police spokesman.

The account of Monday’s incident was similar to that of the others reported since late summer: A man approached from behind, grabbed the victim, touched her inappropriately and fled when she turned around.

The incidents have occurred since late summer.
