An effort to help a Mastic woman move from her home Friday escalated into the stabbing of two men and an arrest, Suffolk police said.

It’s not clear what started the noontime fight at the home on Mastic Boulevard, but another resident there, David Schermerhorn, 61, stabbed one man in the back and another in the shoulder, police said.

The men involved were helping the woman move out of her home, police said.

Schermerhorn is scheduled to be arraigned Saturday on a charge of second-degree assault.
