Acting on a request from the German embassy, immigration police arrested Elmar Anton Schorosch, 50, and Ralf Dotterweich, 51, in separate raids on Monday, the Manager newspaper reported.
Schorosch was arrested in his home in Si Sa Ket province, 435 kilometres north-east of Bangkok, where he had been living for years with his Thai wife. He faces an arrest warrant issued by a Wuerzburg court for fraud.
Dotterweich, who faces an arrest warrant in Wuerzburg in connection with a 500,000-euro (724,000 dollars) tax evasion case, was arrested in Pattaya, a beach resort situated 100 kilometres east of Bangkok.
The two arrests were the latest of several involving German nationals wanted for crimes committed at home.
"Our cooperation with Thai immigration police has really improved over the past year," a German embassy source said.
Thailand's Immigration Police Chief Lieutenant General Wuthi Liptapallop took up his post last year with a promise to crack down on paedophiles and other foreign criminals and living in Thailand, once seen as a safe haven for expatriates fleeing criminal charges in their homelands.//DPA
