A Bronx man was arrested last week for bringing a jar full of deadly toxins to a police precinct.
Police say Jonathan Norling walked into a Pelham Parkway stationhouse holding a container of cyanide Friday.
He was charged with possession of a potentially deadly poison and placed under psychiatric evaluation.
Investigators say the 27-year-old told them he had another jar containing a ricin-like substance in his Allerton apartment.
Police searched the home but it's unclear if they found anything.
Two people were taken to the hospital and have been released.
