A man suspected of aiding in the distribution of drugs discovered in a New York daycare, where a one-year-old tragically lost their life due to exposure to fentanyl, has been apprehended by law enforcement.

Renny Antonio Parra Paredes, aged 38, becomes the third individual arrested in connection with the recent death of Nicholas Dominici.

Following a thorough search of the Bronx daycare facility, significant quantities of narcotics were uncovered. During an inspection of the suspect's residence, authorities identified a stamp used for marking drug packages.

Mr. Paredes faces charges related to conspiracy for the distribution of narcotics resulting in a fatality.

According to the Drug Enforcement Administration (DEA), Mr. Paredes is believed to have played a significant role in an alleged drug trafficking operation operating from the Divino Niño daycare center.

Police were summoned to the facility on September 15th in response to a suspected drug overdose, which resulted in four children falling ill due to the presence of drugs located in close proximity to their sleeping area.

Toddler Nicholas Dominici later died.

"Traffickers often hide contraband in inconspicuous or unsuspecting locations with no regard for the safety of others," said DEA Special Agent Frank Tarantino in a statement announcing the newest arrest.

"In this case, the daycare's floorboards were used as concealment, putting children's lives at risk who innocently sat on the floor to play."

The nursery's owner, Grei Mendez, 36, and her tenant, Carlisto Acevedo Brito, 41, are facing federal charges of narcotics possession with intent to distribute resulting in death, as well as conspiracy charges.

A lawyer for Ms Mendez has said she denies the charges and was unaware that drugs were being kept in the nursery.

A search of Mr. Paredes' apartment revealed devices used to prepare narcotics, prosecutors say, including digital scales and plastic bags.

Police say the drugs found at the daycare bore a "Red Dawn" stamp. The search of the suspect's home also turned up similar packaging and a stamp with the words "Red Dawn".

US Attorney Damian Williams said the arrest "is one more step toward obtaining justice for the child victims of this heinous offense and their families".

Police are still searching for the husband of the daycare owner, who was seen on CCTV leaving with large bags before police arrived.

Investigators believe he may have fled to the Dominican Republic, police sources told CBS News, the BBC's US partner.
