The gunman who opened fire on police officers on a famous Paris street on Thursday was carrying a note praising the Islamic State in Iraq and Syria (ISIS), a French anti-terrorism prosecutor said Friday.

The shooter was identified as 39-year-old Karim Cheurfi, a serial criminal offender who has tried to attack police officers in the past. Cheurfi fatally shot one police officer on the Champs Elysees on Thursday and seriously wounded two others, before being shot and killed by police.

In a Friday news conference, prosecutor Francois Molins said that a note defending ISIS was found near Cheurfi's body and had apparently fallen out of his pocket, The Associated Press reported. ISIS claimed responsibility for the attack Thursday.

Molins said Cheurfi was arrested in February but was released due to lack of evidence, according to the AP. 

The attack on Thursday came just three days before French voters are expected to go to the polls to cast their ballots in the first round of the country's presidential election. Terrorism has become a major issue in the race amid a rash of attacks in the country in recent years.
