Last month, police say a man told Manhattan subway riders that he had a "bomb and I'm not afraid to use it." Now investigators have released a sketch of the person, who is "wanted for questioning in connection to making terroristic threats," and hope the public can help identify him.

The incident occurred on January 5th, around 6 p.m. on a 6 train. According to the NYPD, as the train was heading north from Lexington Avenue and 86th Street, the man yelled, "I have a bomb and am not afraid to die," panicking and alarming fellow riders.

The suspect fled and no injuries were reported.

Police describe the suspect as being about 25-35 years old and 5'5"- 6'0", and was last seen wearing a black coat, blue jeans and a knit hat.

Anyone with information in regards to this incident is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
