Police investigating the deadly Bangkok blast said they were seeking a Thai woman and an unidentified man after bomb-making materials were discovered over the weekend in a second apartment raided by police.

In a televised broadcast on Monday national police spokesman Prawut Thavornsiri showed a photograph of the wanted Thai woman, taken from an official identity card, showing her wearing a black hijab.
