Thailand's Department of Special Investigation (DSI) is preparing to issue its first witness summons to Israeli businessman Maimon David Marciano over suspected use of Thai nominees in businesses and property holdings.
Justice Minister Pol Lt Gen Rutthapol Naowarat said Marciano is not currently a suspect, but investigators want him to explain arrangements involving law firms, hotels and condominiums in Chonburi. Authorities say the assets linked to him in eastern Thailand are worth more than 1 billion baht.
DSI examining Chonburi property network
Speaking after a Justice Ministry meeting in Bangkok on 9 September, Rutthapol said the DSI had obtained substantial information during raids at three locations in Chonburi on 21 August 2026, including sites in Bang Lamung and Pattaya.
Investigators are reviewing documents found during the searches, including property ownership papers connected with other areas, notably southern Thailand. The DSI believes there may be a wider network requiring further legal action.

Marciano is linked to KT International Law and Business, a legal office in Chonburi. Rutthapol said investigators had found indications that Thai nationals had been placed in management roles at legal and accounting firms on his behalf, potentially allowing foreign interests to hold land through legal loopholes.
The minister said there was, so far, no evidence of state officials assisting the arrangements. He added that the DSI needed more time to examine the evidence before taking further steps, but expected action within September.
Eastern and southern provinces under scrutiny
Rutthapol said the DSI will concentrate its foreign-capital investigations in eastern provinces, while police focus on the South. Agencies will share information as they investigate possible links between companies and individuals across regions.
He said some company directors listed in southern provinces had also appeared in landholding records in the North East. The DSI believes Israeli business figures operating in different parts of Thailand may know each other and could share Thai legal or accounting advisers.
The DSI is also examining information concerning Yosef Chaim Kanter, described as a leader of Thailand's Chabad network, after his name reportedly appeared in connection with substantial property holdings. Officials may initially open a separate inquiry before deciding whether it should be combined with other cases.
