This was the ladder leading to a secret cannabis farm hidden in a loft after police raided a home earlier this week.
Officers visited the property at about 8pm on Monday after suspicions were raised about an address on the Bakers Green estate in Huyton.
After going inside the Brookwood Road home, a search led police to the loft area where a Class B growing operation was underway.
Thirty plants were recovered along with associated growing equipment during the Knowsley visit.
A ladder was needed to access the secret area where cannabis plants were lined up in rows and the room was heavily insulated.
Heat lamps were used in the growing operation and a large amount of electricity used to cultivate the illegal crop.
Police arrested two people - a 39-year-old man and a 37-year-old woman - and took them into custody.
They were interviewed by detectives on suspicion of production of cannabis and abstracting electricity.
They have since been released under investigation.
Scottish Power was contacted by police as there was evidence the electricity had been tampered with.
At the start of May, police told how as many as 3,000 plants have been found in the previous six weeks alone, double the figure over the same period last year.
Cannabis factories have been regularly uncovered across Merseyside during lockdown.
In May, a significant grow consisting of more than 500 plants straddling two neighbouring flats was uncovered on Aigburth Road - leading to men jumping through windows and scaling walls.
That seizure mirrored a similar discovery when another cannabis cultivation complex was found at an address on Osborne Road in Tuebrook.
The operation involved a growing scheme extending across seven rooms and three floors.
In April, police busted one cannabis farm chanced upon a second - in the house next door.
Can you help us keep Merseyside covered?
Officers searched a house on Edge Lane Drive, Wavertree, which revealed a large cannabis farm housing about 175 plants, spread across three bedrooms and in the attic, worth about £700,000.
As police were finishing the search, they noticed the upper bedroom windows of a neighbouring house had been boarded up.
They knocked on the neighbour’s door and, after a search, found another cannabis farm.
Police have reminded the public of the tell-tale signs cannabis is bring grown secretly which include strange smells and sounds, frequent visits to a property, often at unusual times, gardening equipment being taken inside, windows sealed and curtains permanently closed and birds gathering on a roof in cold weather.
