A man in his 20s died at the The Crown & Arrows pub in Lincoln on Sunday.
Police were called to the pub on Moorland Avenue at 3.54pm on August 16.
Officers found the body of the man in his 20s and the pub was shut immediately to deal with the situation.
They said the death is not being treated as suspicious.
In a now deleted social media post, the Crown & Arrows said it would be closing immediately until further notice “due to unforeseen circumstances.”
