A group of British tourists were enjoying a sunset cruise along the beautiful Zambezi River when they saw something they will never forget — for all the wrong reasons.

Their dream trip along the river, which lies between Zimbabwe and Zambia, quickly turned into horror when they witnessed a grisly act. Having spotted several crocodiles devouring something from a distance, they got closer only to discover it was actually the bottom half of a person.

“All there was to see of him was his trousers,” a local source who did not wish to be named told the UK’s Telegraph.

“We have had no information about anyone missing from villages around us, so we don’t think the man was a local.”

Meanwhile, Zimbabwe conservationist Trevor Lane from the Bhejane Trust confirmed to the African Times Live that they saw “the bottom half of a human.”

“We strongly suspect it was a poacher… Maybe he was wounded and tried to swim across the river.”

Just two days earlier rangers had tried to capture a group of 13 poachers believed to be in the area.

The group alerted authorities but there were no remains by the time they arrived at the scene.
