WESTPORT — One of two 18-year-old New Haven men, charged in connection with a carjacking that left a 64-year-old Uber Eats driver severely injured, was turned over to Westport police Wednesday and arraigned in Superior Court, where according to a published account, his initial bail was doubled.

Tayvion Hart, the fourth person to face charges filed after the March 5 incident outside Golden Pizza on Post Road East, was being held by New Haven police on unrelated charges March 11 when Westport police said he also was wanted for his alleged role in the local case.

Westport police on Wednesday served a warrant on Hart formally charging him with first-degree robbery, conspiracy to commit first-degree robbery, first-degree assault on an elderly person, conspiracy to commit first-degree assault on an elderly person, first-degree larceny and conspiracy to commit first-degree larceny.

Later in the day, he was arraigned on the charges at state Superior Court in Stamford, and his $250,000 bond was increased to $500,000 during the proceedings, according to a report in The Hour newspaper.

Another 18-year-old New Haven resident, Giovanni Abreu, was arrested on the night of the incident after a chase into Bridgeport.

Abreu, previously arraigned on a lengthy list of charges, is being held on $302,500 bond and is scheduled to return to court April 6, according to Superior Court records.

Two additional suspects under 18, also arrested March 5, were turned over to Juvenile Court officials.

The female Uber Eats driver suffered severe head injuries trying to prevent her car from being stolen while she picked up a takeout order from the pizzeria in the Westfair Shopping Center about 7 p.m. March 5.

Hart then allegedly fled the scene in the woman’s Hyundai, followed by the three other suspects in another car — a black Acura reported stolen in Hamden earlier in the day.

Both vehicles sped westward down Post Road East, and were spotted traveling together by a Westport patrol officer stationed on the Sherwood Island Connector.

Neither vehicle stopped when the officer attempted to pull them over, and instead headed onto Interstate 95 eastbound. 

The officer chased them onto the highway, but eventually lost sight of the Hyundai. 

However, he continued to pursue the Acura, which left I-95 at Exit 29 in Bridgeport, where the driver lost control and crashed into an occupied vehicle and several parked cars, police said.

Abreu and the two juveniles were quickly apprehended after the accident by the Westport officer and Bridgeport police.

A gun was later found in the wrecked Acura, although investigators said they do not believe the weapon was used during the Westport incident.
