PINELLAS PARK — Two teenage brothers were arrested after an altercation between the two led to one brother barricading himself in their residence, according to police.

Police arrived at the residence at 5839 62nd Ave. N around 3:30 p.m. Wednesday where the brothers had gotten into a physical fight. Police said the younger brother, 14, had slashed the 16-year-old older brother's hand with a butcher knife and the older brother threatened him with a handgun.

When police arrived, the younger brother and the two boys' mother were waiting outside the home, while the older brother had gone back inside and refused to come out.

A tactical team was called to the residence around 5:30 p.m., but police said there was no visual evidence that the older sibling was still in the house. Instead, negotiators eventually made contact with the brother and found out he was at a food market in St. Petersburg.

The older brother was located by St. Petersburg police and arrested, while Pinellas Park police arrested the younger brother.

They both face felony assault charges, police said.

Police were still trying to locate the firearm Wednesday evening and figure out how the older brother got it.
