Two people died and 10 others were hospitalized after being poisoned while taking part in a group therapy session in Berlin, German police said on Sunday. One person is in critical condition in a coma.
The doctor who led the session has admitted giving the participants various substances and drugs during the meeting, Martin Steltner, a spokesman for the Berlin prosecutor's office, told The Associated Press on Sunday.
Altogether 14 people participated in the session. Twelve were taken to a hospital in Berlin on Saturday night after one of them called the emergency services.
The doctor was detained and a homicide division was investigating the case, police said.
