Fall River — A reported car jacking, a crash and an attempted second carjacking ended at gunpoint near The Herald News on Pocasset Street Thursday morning when police apprehended an unidentified young man without incident – helped by an alert tractor-trailer delivery driver who blocked his running path.

“I saw two cops chasing him with guns out. He went back to grab the lady’s car. I said, ‘Stop, stop for the police, stop for the police,’’ said Mannuel Machado, 59, of Somerset, after pulling his 60-foot rig across Pocasset Street.

He said the suspect, who appeared to be in his early 20s with short-cropped hair wearing a black T-shirt and jeans, reversed direction when the tractor-trailer blocked his path. The suspect then tried unsuccessfully to open a white car with a female driver but the car was locked, he said.

Somerset Patrolman David Labreche said police in that town recognized the blue 2008 Honda Civic that was carjacked earlier from the 7-11 on Milliken Boulevard.

City police, who arrested the man, were not available for comment.

Driving back into Fall River and pursued by multiple police cruisers, the stolen car crashed on the nearby I-195 West overpass, Labreche said. The man fled on foot, pursued by Labreche and Somerset Lt. Stephen Moniz, Machado related shortly after 10:30 a.m.

“Within two seconds there were like 30 cops all around him,” said Machado, who delivers weekly inserts at The Herald News for New Penn Motor in Lebannon, Penn. from their Cumberland, R.I., office.

Machado, a married father with a 4-year-old granddaughter, said, “When I saw the cops coming up and the guy running, I knew something was wrong.”

Asked how he felt assisting in the arrest, Machado, a 34-year Somerset resident, said, “After something like this, it’s always good to be on the right side and help the police.”

Lebreche shook his hand and thanked Machado for his assistance

Witnesses at the 7-Eleven at 340 Milliken Boulevard said a man forced a young woman at knifepoint to give him her car right outside the store's front door t about 10:30 Thursday morning.

Joliene Cardoso, who was working behind the counter at the store, said she didn't hear a commotion but that the woman ran into the store out of breath saying she had been carjacked.

"She was pretty freaked out," Cardoso said. "It's crazy."

A male customer said he saw the alleged carjacker "lurking around" the convenience store.

Louis Vasconcellos, who listened to the incident on his police scanner and watched from outside his 19th floor Ship's Cove apartment window, said he saw the alleged carjacker jump from the Milliken Boulevard overpass onto Pocasset Street, while it looked like police officers were trying to subdue him with taser guns.

"Within a matter of minutes, the whole city of Fall River was there," Vasconcellos said of the police. There were at least 20 Fall River, Somerset and state police cruisers, he added.

On his police scanner, Vasconcellos said he heard that the alleged carjacker was driving 90 mph over the Brightman Street Bridge from Somerset to Fall River. Vasconcellos said he saw the alleged carjacker jump from the Milliken Boulevard overpass and hide under a Herald News delivery truck.

Lori Cameron, a 7-Eleven manager, said she was glad there were enough customers at the store that the alleged carjacker didn't try to rob the store.

"We're getting robbed too much," she said. "They need to do something. This town is getting crazy."
