Authorities are asking for the public's help to identify the suspect arrested and shot after a jewelry store heist in Woburn Tuesday.
The Middlesex district attorney's office today released photos of the suspect's tattoos.
He remains hospitalized in serious condition after being shot by police while fleeing from Musto Jewelers.
"Authorities have not yet been able to identify the man, who had not identifying information on his person when he was apprehended," the DA's office said.
Woburn Police Officer Robert Denapoli was also shot when he responded to the robbery. He is still hospitalized.
Authorities are still searching for two or three additional suspects who were able to flee during the violent robbery.
Anyone with information can call 781-933-1212.
