Written and executive produced by Matthew Parkhill, the series will show an origin story of the well-known detective in "an explosive reimagining of this iconic character".
As per the log line for the series, "Sherlock Holmes is disgraced, raw, unfiltered, and unformed" when he is caught up in a murder mystery at Oxford University "which threatens his freedom".
It continues: "Diving into his first ever case with a wild lack of discipline, Sherlock manages to unravel a globe-trotting conspiracy that will change his life forever."

Further casting is yet to be announced, with Tiffin the only actor confirmed to be starring so far.
Ritchie and Tiffin previously worked together on The Ministry of Ungentlemanly Warfare, but many may recognise Tiffin from his role as Hardin Scott in the After film series.
"In Young Sherlock, we're going to see an exhilarating new version of the detective everyone thinks they know in a way they've never imagined before," said Ritchie.
"We're going to crack open this enigmatic character, find out what makes him tick, and learn how he becomes the genius we all love."
Simon Kelton (Eddie the Eagle), Ivan Atkinson (The Gentlemen), Simon Maxwell (The Woman in the Wall), Dhana Gilbert (The Marvelous Mrs Maisel), Colin Wilson (The Mandalorian) and Marc Resteghini will also executive produce. Harriet Creelman will serve as co-executive producer.
