Four people were arrested after two separate riots were reported in a single day.

DK Joywell, 19, Yos Yos, 26, Mase Joywell, 19, and Ataf Yos, 19, were each charged with aggravated assault as a third-degree felony with a special allegation of possession of use of a deadly weapon in the commission of a felony, rioting as a third-degree felony and public drunkenness as a violation. Yos Yos was also charged with resisting arrest as a misdemeanor.

According to court documents, police responded to a complaint near Guam Premier Outlets in Tamuning. The victim told police the suspects threw a beer can at him before the group got out of the car and surrounded him.

Joywell allegedly tried to hit the victim in the head with a metal pipe, as the three others had him cornered, the prosecution alleged in court documents.

The victim was able to block the pipe with his hand. The suspects took off from the scene before police arrived. The victim was treated for his injury at Guam Memorial Hospital.

Soon after the Tamuning incident, police received a call of a riot at the Paradise Toves Mart in Dededo. Officers spotted a vehicle that matched the description of the car the suspects involved in the alleged attack in Tamuning were using, documents state.

Witnesses told police the suspects had been fighting unknown individuals who had fled the area. One of the Joywells allegedly tried to shoot several others with a slingshot before they ran away, documents state.

As officers questioned Joywell, Yos Yos allegedly stepped between the two and pushed the officer away, documents state. After a brief struggle with police, Yos Yos allegedly kicked the officer's patrol car and challenged him to fight.

All four were intoxicated when the alleged incident occurred, documents state.
