Popular Moroccan rapper ElGrande Toto was taken into custody on Monday evening, the AFP news agency reports quoting a judicial source.
It followed complaints filed against him for public statements he made about using cannabis.
The rapper, who has a big following in the country, is reported to have told journalists last month that "I smoke hash - so what?... It does not mean I set a bad example".
His comments sparked an outcry in Morocco, and the 26-year-old was on Thursday forbidden from leaving Casablanca and was also summoned by the police, AFP reports
A prosecutor late on Monday placed Taha Fahssi, ElGrande Toto's real name, in custody after complaints were filed by "three artists, a journalist, and a policeman", the news agency quoted the judicial source as saying.
He was taken into custody a day after apologising for his comments.
