ROMANS: Police say they are now looking for a woman wearing a black shirt in connection with this week's deadly Bangkok shrine bombing. Thai authorities say at least 10 people, 10 people may have taken part in that bombing. But the attack, they say, is not likely to be linked to international terrorist groups. CNN's Andrew Stevens is in Bangkok for us for the latest -- Andrew.</s>ANDREW STEVENS, CNN ASIA-PACIFIC EDITOR: Police in Bangkok now say they think at least 10 people were involved and what they say was a well-organized team that executed the attack on Erawan Shrine on Monday evening. They say they've obtained evidence to suggest that several people were involved in plotting the attack and also acquiring the materials, as well as building the bomb. All done under the radar, of course. They haven't shared what that evidence is at the moment. At this stage, they also are pulling back on making any link with international terrorism. They say they've been talking to Interpol. They've also been sharing information with security agencies in the U.S., the U.K. and Australia, and the consensus opinion is that it is not an international conspiracy which brings the focus at least somewhat back on to domestic issues. And they say they're not ruling anything out at this stage. They've meanwhile increased the reward for any information leading to the arrest of the man in the yellow shirt. The man they say they are now very sure is the bomber. Apart from the early breakthrough when they identified the man they think as the bomber, there's been very little else solid and concrete. They've actually ruled out two other suspects they thought were initially accomplices. And they are now saying that the network that was used may be more than 10 people. Very frustrating for the police, but also very frustrating and also very worrying for the people of Bangkok. Andrew Stevens, CNN, Bangkok.</s>ROMANS: All right. Thanks for that, Andrew.
