Lynn man held without bail after chasing woman into police station lobby while wielding large knife

LYNN – A Lynn man remains in Middleton Jail without the option of bail after he allegedly chased a woman into the Police Department?s main lobby while wielding a large kitchen knife, according to an arrest report.Officer Raymond Therrien reported seeing the 42-year-old woman being “chased frantically” toward the department entrance by a man later identified as Constantine Greven, 40, of 26 Washington St. The woman entered the lobby and “quickly began to cower.” Therrien quickly noticed Greven had a large kitchen knife in his hand and was raising it toward her while striking her with a closed fist, according to the report.Therrien radioed for help, then grabbed Greven?s right arm and “delivered several knee strikes to his midsection” until he dropped the knife, the report said.The woman told police she had been riding her bike down Washington Street when she noticed Greven, with whom she had an “on and off” two-year relationship, the report said. Greven went inside and retrieved the knife, and then “swung it wildly, nearly missing her and her bike.”Greven also allegedly threatened the alleged victim and others on the street, saying, “Today is a good day to die. I?m not going back to jail, someone is going to die,” according to the report.Greven was charged with assault with a dangerous weapon, violating the knife ordinance, violating a restraining order, disorderly conduct, resisting arrest and assault and battery on a police officer.The alleged victim, who had an active restraining order against Greven that ended today, chose not to renew the order during a District Court hearing Monday.Judge Albert Conlon ordered Greven held without bail at the hearing, and he is due back in court July 25 for a pre-trial hearing.Taylor Provost can be reached at [email protected].
