The suspected gunmen wanted in a Bronx shooting that wounded four people — including a 3-year-old boy and his 6-year-old brother — last week have been arrested, police said Thursday.

Mikel Taylor, 16, and Angel Hernandez, 20, were busted Wednesday night and each charged with four counts of attempted murder for the July 11 shooting, cops said.

The pair allegedly opened fire into St. James Park, at the corner of East 193rd Street and Morris Avenue in Kingsbridge, where hundreds of people had gathered on the warm summer evening, according to police.

A 6-year-old boy was struck in the right calf by a stray bullet and his younger brother, age 3, was grazed in the hail of gunfire.

A 25-year-old man was also shot once in the back. His 23-year-old cousin — believed to be the intended target of the violence, according to sources — was shot in the left thigh, cops said.

All the victims survived.

The gunmen took off on a scooter, cops said.

The NYPD released images and video of the suspects in the aftermath of the shooting.
