Four men got out of the minivan and tried to attack police officers by using samurais. The police shot dead the four.
The minivan`s driver, in an attempt to flee, hit a police officer until he died, and injured a television journalist.
The driver was later arrested by the Riau police.
Earlier, the Riau Provincial Police confirmed that they had shot dead four terrorists attempting to attack the Riau Police Headquarters in Pekanbaru on Wednesday.
Adjunct Senior Commissioner Sunarto, spokesman of the Riau Provincial Police, informed the press here on Wednesday that the four were shot dead after getting out of a minivan earlier used to attack police officers.
The four were armed with samurais and tried to attack the officers.
