Man posts hilarious TripAdvisor-style review of his '4-star' jail cell

Willoughby shared photos of the food -- “lovely,” he deemed it -- his cell's toilet and an assortment of other scenes following his arrest on unspecified charges.

“It's the all-day breakfast that lets it down, really,” he wrote. “Apart from that, the staff are pleasant enough. … Ideal place for winding down after a hard day.”

It was not immediately clear how he was able to snap the six photos of his stay at the Grimsby police station. On social media, he claimed the photos were taken on an iPad.

Humberside police told The Guardian they are investigating.

“The force are aware of pictures apparently of the Grimsby custody suite on social media,” Chief Inspector James Glansfield told the newspaper. “We take any such breach of security and detainee safety extremely seriously and will be carrying out a review of our detainee management to identify any lessons learned and prevent further reoccurences in the future.”
