According to police, the individuals were detained for alleged drug use in Park Hayarkon, where the event was taking place. Among those detained for questioning was Boaz Verchtel, founder of Ale Yarok (Green Leaf Party).
Police officers arrived at the event, where some 2,000 people in attendance marked International Marijuana Day, turned off the music, confiscated equipment, and ordered that the event be halted.
Health Minister Danny Naveh (Likud) and MK Roman Bronfman (Yahad), who were to have addressed those in attendance will not speak, as police shut down the stage.
Event organizers plan to convene a press conference during which they will respond to the actions of the police.
Yarkon District commander Aharon Ezra, who was present at the event, said that the event was brought to a halt because, "The party had become a drug party." According to Ezra, some eighty police officers had been present at the part since the morning hours.
Bronfman said that the High Court had rejected a petition by Al-Sam, a drug abuse prevention organization, seeking to cancel the program, and that shutting down the stage at the event equated to speech restriction, and was done so as to prevent him from addressing those in attendance.
Bronfman noted that he had planned to discuss the adverse affects of drug use and his opposition to the use of druge, although he also intended to criticize the state for its policy that does not differentiate between soft and hard druge. Bronfman also said that this is the seventh year in which "Marijuana Day" event has been held, and the first time it has been halted.
