* Says looking at Blockbuster, other overseas opportunities
* SK Tel shares down 0.31 pct in a wider market up 0.64 pct (Adds details, background)
SEOUL, March 30 (Reuters) - SK Telecom , South Korea's top mobile carrier, is considering investing in bankrupt U.S. video rental chain Blockbuster Inc, an official with the operator said on Wednesday.
"We are considering investing in Blockbuster as we are looking at many opportunities overseas," the official said on condition of anonymity, as she was not authorised to talk to the media.
A company spokesperson declined to comment.
SK Telecom, which controls around 50 percent of the nearly saturated domestic market, has been looking for opportunities to invest overseas to generate new revenue streams.
However, its overseas investments so far including those in the United States, have not produced meaningful results, analysts say.
Most recently, SK Telecom bid for Indonesian cable TV and internet firm First Media which parent Lippo Group wants to sell for $400-$500 million. [ID:nL3E7CJ0OW]
Blockbuster will proceed to a sale auction in April after the the bankrupt U.S. company negotiated an agreement with creditors who had called for an immediate Chapter 7 liquidation. [ID:nN10180584]
Blockbuster, which has 2,500 locations, filed for bankruptcy in September after years of struggling to keep up with competition from Netflix Inc and online offerings.
Shares in SK Telecom were down 0.31 percent in a broader market that was up 0.64 percent as of 0201 GMT. (Reporting by Hyunjoo Jin; Editing by Jonathan Hopfner)
