UPDATE 1-Takilant account frozen in TeliaSonera Uzbek probe

* Prosecutors freeze Takilant account with $30 mln

* Request court authorisation to freeze more assets

(Adds detail, background, TeliaSonera comment)

STOCKHOLM, Oct 1 (Reuters) - A prosecutor investigating TeliaSonera's purchase of a telecom license in Uzbekistan has frozen a Swedish account containing $30 million held by the seller, Gibraltar-based Takilant Ltd.

"I have decided, for various reasons, to take that account into custody, which is the equivalent of freezing it. That is all I can comment," Prosecutor Gunnar Stetler told Reuters.

He confirmed that the company in question was Takilant.

Swedish prosecutors last month opened a preliminary investigation into TeliaSonera's purchase after a Swedish television programme alleged the company had bought the license from a firm with close ties to the daughter of Uzbek President Islam Karimov.

TeliaSonera, partially owned by the Swedish state, has denied it did anything wrong when it bought the 3G license to operate in Uzbekistan from Takilant in 2007.

The company has said it will cooperate fully with the prosecutors' probe and appoint independent investigators to look into allegations of bribery and money laundering associated with the deal.

Reuters was unable to reach Takilant for comment.

Court documents obtained by Swedish daily Svenska Dagbladet and published in full on its website showed prosecutors had also requested authorisation to freeze Takilant assets worth at least 1.55 billion Swedish crowns ($236 million).

However, Stetler said the request, submitted to the court earlier on Monday, was a formality since Takilant was not known to possess any assets of that size in the Nordic country.

TeliaSonera Chief Executive Lars Nyberg has staked his job on seeing that the company, in which Sweden owns a 37 percent stake, is exonerated from wrongdoing in the 2.3 billion crown ($352 million) deal with Takilant.

The court documents also cited an investigation by Swedish bank Handelsbanken which prosecutors said had failed to uncover any evidence that Takilant had ever owned a telecom license in the Central Asian country.

A TeliaSonera spokeswoman said the company remained confident that Takilant had owned the license bought by the Swedish group.

"We confirmed that they were the rightful owners," spokeswoman Irene Krohn said. ($1 = 6.5676 Swedish crowns)
