Police arrested 10 additional people on Monday morning in connection with violent incidents during protests in the capital, bringing renewed attention to the authorities’ investigation into clashes that left several officers injured.

According to police, officers carried out early-morning arrests at the homes of the suspects, who are accused of participating in acts of violence and destruction during Sunday’s demonstrations.

The 10 people arrested were identified by police as Altin Koçi, Pajtim Lushi, Eden Bulku, Shkelzen Mujsaku, Orjan Cishkeku, Zyber Muca, Silvi Haxhi, Marlon Ladage, Klejdi Mehaj and Endri Doku.

Authorities said a further 21 people had been arrested on Sunday in connection with the unrest. Those arrests, combined with Monday’s operations, form part of an ongoing investigation led by the prosecution.

In an official statement, police said officers were attacked in several areas of Tirana with stones, screws, metal spheres, wooden and metal sticks, pyrotechnic devices, Molotov cocktails and gas canisters fitted with firecrackers.

Several police officers were injured during the incidents and received medical treatment, according to authorities.

Police said the suspects range in age from 18 to 54. In addition to those arrested, 13 people are facing criminal proceedings without being taken into custody, while 30 others were initially declared wanted. Ten of those wanted individuals were arrested on Monday, and efforts to locate the remaining suspects are continuing.

The investigation aims to establish the full circumstances of the violence, including alleged assaults on police officers and damage to state institutional buildings, according to the police statement.

The latest arrests come amid heightened tensions surrounding protests in Albania. Authorities have said they will continue identifying those suspected of involvement in the clashes and pursuing legal action as the investigation progresses.
