A 40-year-old man allegedly smashed a glass bottle over the head of a police officer during an incident in Co Tyrone.
Two police officers were injured after being attacked in Dungannon in the early hours of this morning.
The PSNI said metal garden furniture was also thrown at the officers who were in pursuit of the suspect.
He was later arrested.
"A man made off from police while two officers attempted to engage with him while on patrol in the Ballygawley Road area of Dungannon at around 12.10am this morning," a PSNI spokesperson said.
"Officers chased and caught up with the man and while they attempted to arrest him, he threw metal garden furniture at both officers and smashed a glass bottle over one of their heads.
"The officers both attended hospital for treatment to their injuries."
The PSNI spokesperson said the suspect was arrested on suspicion of a number of offences, including two counts of attempted grievous bodily harm, two counts of assault on police and two counts of possession of an offensive weapon.
"Assaults on our officers are unacceptable, and must not be tolerated as simply being part of the job," they added.
