Hungarian police have detained four people on suspicion of carrying out illegal, untested stem cell treatments using embryos or aborted fetuses at a Hungarian private clinic, police said in a statement.

The statement, posted on the official police website www.police.hu late on Tuesday, said the suspects — two Hungarians, one U.S. and one Ukrainian citizen — were detained on July 27 just as they were preparing to treat a new patient.

Police said they launched a procedure on “suspicion of a banned use of the human body.”
