"There are serious, consistent and credible allegations of excessive use of force, in particular excessive and improper use of tear gas and ill-treatment during and after apprehensions," Muiznieks said in a statement. "These raise very serious concerns, requiring a determined response from the Turkish authorities."
Muiznieks' report warns that a failure to conduct independent investigations will result in numerous cases being referred to the European Court for Human Rights. The court oversees the implementation of the European Convention on Human Rights, which all 47 members of the Council of Europe, including Turkey, have signed.
The Council's report also raises concern about moves by the Turkish government to investigate groups that aided demonstrators, including doctors and lawyers.
"The Commissioner also expresses deep concern about a climate of fear of reprisals by administrative and judicial authorities for non-violent involvement in the Gezi events," the report says.
The report also cites numerous incidents of mistreatment of journalists trying to cover the protests.
