On 12/10/18, at approximately 8:30 p.m., a subject entered a jewelry store and used pepper spray to incapacitate the storeâ€™s security guard. The subject then used a hammer to breach a glass display case. He took jewelry and then fled from the store. Approximately one week prior to this incident, another smash and grab occurred in Clinton Township, MI. In that incident, three robbers entered a store shortly before 8:30 p.m. After smashing display cases, subjects then proceeded to escape with 150 diamond rings valued at more than $100,000. Detectives in Troy, MI and their colleagues in Clinton Township will consultÂ to determine if the two events are connected. Clinton Township Detective Capt. Richard Maierle,Â has stated, “Wer’reÂ thinking this possibly could be a loosely organized gang.” If you have any information regarding these incidents, please call the Jewelersâ€™ Security Alliance at 212-687-0328.
