A Bridgeport man, who tried to evade officers by jumping into a river, has been arrested after police say he threatened to kill a man – then showed up to his house with a loaded gun.

Tryronn Anyanwu, 32, is charged with criminal possession of a firearm, stealing a firearm, possession of a large capacity magazine, sale of a narcotic substance, possession of a controlled substance, interfering and second-degree breach of peace.

The incident happened around 10 a.m. Monday in the High Rock part of Shelton. Det. Richard Bango said the victim called police stating Anyanwu sent him threatening text messages.

"They were arguing over something and he said he was going to come over there and kill him," Bango said.

Bango said the responding officers saw Anyanwu in the victim's driveway and ordered him to come out of his car.

"He immediately ran. He encountered a river, which was on the high side because we had so much rain. He jumped in and tried to swim across, but he failed," Bango said.

Bango said Anyanwu swam back and was taken into custody. He said officers found a stolen semi-automatic gun with a banned high capacity magazine in Anyanwu's car. Police also seized 44 wax folds of heroin, 11 grams of cocaine and other drug paraphernalia, Bango said.

Court records show Anyanwu was previously arrested on drugs and weapons charges several times over the past decade. Bango credits the victim for calling police immediately.

"Not only did [Anyanwu] show up to his house, he showed up with a loaded gun. I can't say for certain what he was going to do, but it does show some intent. It's scary," Bango said.

Bango said it's unclear Anyanwu and the victim's exact relationship and what their argument was over.

Anyanwu was released after posting a $100,000 bond. He's due in court on May 23.
