A 28-year-old Medford man is due in court this afternoon after state police say he randomly stabbed another man with a screwdriver in front of a Medford Starbucks, an alleged attack that left a bloody scene in front of the business as customers sat with their morning coffees.

Troopers arrested Junior Dornevil after he fled toward the Wellington MBTA station after stabbing a man in the face, leaving him with non-life-threatening injuries, state police said.

Troopers at the Medford barracks, which is located across the street from the Starbucks, rushed to the scene about 9:30 a.m. and were told Dornevil had taken off on foot, police said.

Police say the incident appears to be random and a preliminary investigation showed the men do not know each other.

Dornevil was booked on assault-related charges and will be brought to Somerville District Court for arraignment.

The brazen, daylight attack left a large bloodstain on the sidewalk in front of the Starbucks.

In addition to the screwdriver, Dornevil was also carrying a saw, police said, which could be seen on the ground in its sheath.

Customers inside the coffee shop were unsure of what had occurred, but rattled by the alleged attack.

“This is a nice neighborhood, I get my coffee here every morning,” said Terry Lall as she walked out of the Starbucks with her husband. “I’m surprised, we really are shocked. We don’t have this around here.”

Dornevil was already due back in Somerville court next month for a bench trial after being charged with randomly punching a man last March. The victim in that incident said he had been waiting for a bus in front of 607 Fellsway when Dornevil walked up to him and punched him in the face before walking away, court documents show.

Dornevil is scheduled to stand trial for the misdemeanor assault April 12, documents show.

The victim in the March, 2016 attack called Medford police and followed Dornevil until they arrived and arrested him, documents show, adding the suspect accused the victim of “making faces at him.”

Dornevil was also arrested on numerous other charges, including assault and battery with a dangerous weapon, disorderly conduct, and destruction of property, documents show, and was acquitted in a bench trial in March 2014.
