Police are trying to identify the "organic substances" that were found inside a vacant Philadelphia building.
Police arrived at an abandoned building on the 900 block of Spring Garden Street around 5:45 p.m. on Tuesday after receiving reports of a strange smell. Once inside, officers discovered several substances on the second floor of the building.
Police initially told NBC10 the substances were marijuana, mushrooms and drug-making chemicals. They later reported however that they were not marijuana plants and instead described them as "organic substances." They continue to investigate.
A person of interest in connection to the substances was taken into custody. He or she has not been officially charged.
