Norwegian police said on Friday they had issued an international arrest warrant for a second suspect in a June shooting that killed two people near a gay bar in central Oslo.

The police first indicated at a press conference that they were looking for, for “complicity in a terrorist act”, a Norwegian man in his forties who had already appeared on police radar and currently believed to be abroad.

They then confirmed a TV2 report that the suspect was Arfan Qadeer Bhatti, a 45-year-old man with previous convictions.

They did not say what role he may have played in the shooting, or where he is currently.

TV2 said Bhatti was in Pakistan, which does not have an extradition treaty with Norway.

Police said cooperation with the country concerned was positive and extradition was a “possibility”.

The first suspect, Zaniar Matapour, allegedly opened fire near a gay bar in central Oslo in the early hours of June 25, during celebrations related to the city’s Pride festival.

The shooting killed two men, aged 54 and 60, and injured 21 others. Matapour, 43, was quickly arrested.

Matapour, a Norwegian of Iranian origin, had been known to Norwegian intelligence services from the PST since 2015. There were concerns about his radicalization and membership in “an extremist network”.

Norway‘s domestic intelligence service described the attack as “an act of terrorism” and said Matapour had “mental health issues”.

He is currently in a mental hospital for a court-ordered mental evaluation.
