Most of the rallies passed peacefully, though many broke rules on social distancing, prompting officers to intervene and arrest dozens.
Police in Saxony said the incident one officer was bitten on Monday while trying to check the identities of people at a demonstration. Several of the protesters attacked police and sprayed them with chemical irritants.
“One person attempted to seize an officer’s service weapon and another police officer suffered a bite wound from a participant of the gathering,” Saxony police said in a statement.
