A second suspect in the murder of Hamas official Mahmoud al-Mabhouh was arrested by authorities in an unnamed Western country two months ago, a newspaper in the United Arab Emirates reported Monday.
The National daily quoted the head of the Dubai police force, Dahi Khalfan Tamim, who has been in charge of the investigation into the January murder, DPA reported.
The newspaper suggested that the country where the suspect was arrested is "Western," but not European.
"The suspect who was arrested played a key role in the killing, but we were informed by the ambassador (of the country involved) during a meeting that they did not wish to release the information," Tamim told the paper.
He also called for more transparency.
"Why is it that every time an Israeli is involved in a crime, everyone goes mute?" Tamim asked.
Dubai authorities used closed circuit TV footage to identify suspects in the murder which took place in January. They said the assassination was most probably carried out by a large hit-squad from Mossad, Israel's intelligence agency.
The murder sparked international outrage, as citizens from several nations, including Germany, Ireland and France, had had their identities stolen by the perpetrators who travelled to the UAE to carry out the killing.
In June, suspected Israeli intelligence agent Uri Brodsky was arrested in Warsaw under a European arrest warrant requested by Germany for alleged involvement in passport fraud in relation to the case
Brodsky, the first individual arrested in connection with the killing, was extradited to Germany and released on bail in August.
