Lamarr Chambers, 24, was arrested in Harlow, Essex, on January 17 and officers tweeted updates of what they described as "poo watch" until the force decided to release him from custody on March 5 "following medical and legal advice".
Charges of intent to supply a class A drug and driving matters were discontinued but Chambers was rearrested by Essex police on suspicion of being concerned in the supply of a class A drug and was released on bail before being taken to hospital.
Police had applied for custody extensions at seven court hearings as they waited for Chambers, of Brixton, London, to go to the toilet.

Officers said Chambers was seen daily by doctors, was constantly watched and routinely supplied with food and water.
Chief Constable BJ Harrington is quoted in the Daily Mail as saying: 'Police forces have a legal and ethical responsibility for the welfare of anyone brought in to police custody. Although an investigation concerning the supply of Class A drugs is routine for our officers, there have in this case been some highly unusual circumstances which have attracted national attention."
