Hundreds of students march in the Haitian capital Port-au-Prince, shouting and waving signs against the National Police.
They're angry over the weekend death of a university student -- allegedly shot by a police officer at a party.
But the protest erupted into clashes as demonstrators threw rocks at police, who responded with tear gas.
The unidentified police officer accused of fatally shooting twenty-four-year-old Damael d'Haiti on Saturday has been taken in for questioning.
The investigation, however, has done little to quell anger.
According to authorities, several students were injured in the clashes.
