Police in Łódź Discover Secret Marijuana Plantation Hidden Behind a Wardrobe Hole

Police officers from the Narcotics Crime Division of the Municipal Police Headquarters in Łódź dismantled a hidden marijuana plantation on Wednesday, March 25, 2026, after discovering a secret room concealed behind a hole in a wardrobe wall inside an apartment on Sienkiewicza Street in the city center. Officers arrested a 46-year-old man as he was leaving the premises and, following his admission that he kept drugs in a jar inside the flat, conducted a search that revealed far more than a simple possession case. The strong smell of cannabis permeating the apartment prompted investigators to look more closely at the wardrobe, where a small opening in the wall led to a professionally equipped growing room. Officers secured 11 cannabis plants, nearly 21 grams of dried marijuana plant matter, and over 10 grams of dried stems. The man now faces charges of drug possession and illegal cultivation of marijuana, carrying a maximum sentence of up to three years in prison.

Secret room equipped with professional growing systems The hidden cultivation space was outfitted with specialized equipment designed to sustain a functioning indoor plantation. According to aspirant Kamila Sowińska, press spokeswoman for the Municipal Police Headquarters in Łódź, the room contained appropriate lighting, ventilation, heating, and irrigation systems — the full infrastructure required for cannabis cultivation. One of the officers physically squeezed through the hole in the wardrobe wall to access the concealed space, according to reporting by Dziennik Łódzki. The plantation was located in a tenement house in the Śródmieście district, one of the central neighborhoods of Łódź. The level of technical preparation suggested the operation was not improvised but rather deliberately constructed over time. „The discovered room was equipped with specialized equipment necessary for growing cannabis, including appropriate lighting, ventilation, heating and irrigation. In total, the following were secured: nearly 21 grams of dried marijuana plant matter, over 10 grams of dried stems of the plant, and 11 cannabis bushes” — Kamila Sowińska via Dziennik Łódź

Arrest came as suspect walked out the door The operation began after officers received information through operational means suggesting that the tenant of the Sienkiewicza Street apartment was in possession of drugs. When the team arrived at the address, the 46-year-old suspect was already stepping out of the building, and officers detained him immediately on the spot. During an initial conversation, the man admitted to keeping marijuana in a jar inside the apartment, which led to a formal search of the premises. The jar was confirmed during the search, but investigators treated it as only a partial finding given the overwhelming smell of cannabis throughout the flat. The suspect was subsequently charged during questioning, and the case was referred to the court. 3 (years) — maximum prison sentence the suspect faces

Łódź narcotics unit targets urban drug cultivation Indoor cannabis cultivation operations hidden within residential apartments have become a recurring challenge for Polish law enforcement in urban centers. Łódź, Poland's third-largest city by population, has seen periodic enforcement actions targeting drug production in its densely populated central districts. Polish law criminalizes both the possession and cultivation of cannabis regardless of quantity, with penalties scaling based on the scale of the operation and the intent of the cultivator. The case highlights the use of concealed architectural modifications — in this instance a hole cut through an interior wall — as a method for hiding cultivation equipment from routine inspection. The Sienkiewicza Street address sits in the heart of Łódź's historic tenement district, where older building layouts can provide spaces suitable for concealment. Aspirant Kamila Sowińska, whose role as press officer for the Municipal Police Headquarters in Łódź was confirmed by official police records dating to 2019, served as the official source for all operational details released to the media. The charges filed against the 46-year-old cover both possession and cultivation, reflecting the dual nature of what officers found — stored dried material alongside living plants in an active growing environment. The case was reported by multiple regional outlets on March 27, 2026, two days after the arrest took place.
