Department of Special Investigation officials trying to smash the smuggling of Rohingya through Thailand to Malaysia hope to be able to seek arrest warrants for Thai traffickers in coming days. DSI staff are also questioning Rohingya who work as roti vendors in Bangkok for any clues about trafficking gangs. Thirteen illegal Rohingya immigrants were rounded up in Bangkok on Wednesday. Among the Rohingya who were arrested with their roti vending carts were three minors who were held by DSI authorities as witnesses to help track down the traffickers. According to sources, roti vending provides temporary work for illegal Rohingya migrants who are waiting in Bangkok and southern provinces for their departure to Malaysia, which is a favourite destination for them as they are Muslims.
