Minutes after authorities named him, police said detectives in Queens tracked down Daniel St. Hubert and arrested him in connection to the stabbing death of a boy in East New York.
NYPD said late Wednesday that St. Hubert, 27, was collared by detectives shortly after 8 p.m. near 145th Street and 133th Avenue in Queens and taken to the 106th Precinct station house.
At nearly the exact same moment, Mayor Bill de Blasio joined Police Commissioner Bill Bratton, Chief of Detectives Robert Boyce and Brooklyn Borough President Eric Adams to release St. Hubert's wanted poster.
Authorities disclosed Hubert's name in connection to the death of P.J. Avitto, 6, and severe injuries to Mikayla Capers, 8, on Sunday. Bratton said investigators had not yet conclusively linked St. Hubert to Friday's stabbing of 18-year-old Tanaya Copeland.
St. Hubert was released on parole on May 23 for a domestic assault and had nine prior arrests. Boyce said he has also displayed a history of violent behavior, having attacked a police officer and corrections officer.
Boyce declined to say if St. Hubert was considered as emotionally disturbed.
