An armed robber held up a teacher at gunpoint inside a small arts school in a Jamaica Plain neighborhood Wednesday night. The incident, along with a second robbery in the area Thursday night has police stepping up patrols in the area near Eliot Street, an area considered a walking neighborhood near Monument Square.

On Wednesday night, a suspect described as a black man in his 20's, about 5-feet-8 inches to 6-feet-1 inches tall, medium build and wearing a hoodie made his way to the second floor of the Eliot School of Fine and Applied Arts.

Executive Director Abigail Norman says he showed a weapon and demanded the teacher's wallet and cellphone.

"He (the teacher) had a lot of poise, lived in the city his whole life, and knew to give the stuff away," she said.
