Protesters had gathered near where Mauricio Fredes died after being pursued by police during the 'social outbreak' wave of protests in 2019, a movement that is still ongoing.
Fredes died at the age of 33 on December 27 2019, when he fell head first into a water-filled pit containing electrical cables as he was attempting to escape from a pursuing police vehicle during a protest.
As a result of the protests, Chile voted for a new constitution in a referendum in October, which saw an approval rate of 78 percent.
