The summons would be issued tomorrow so Palita Lakchalermporn could be interviewed on Thursday, a police source said.
Her business partner is Sudatip Muangnual, 45.
The source also gave a progress report on Lat Phrao police’s investigation into Chakarn Parkpoom and Natthapol Suwadee for allegedly committing lese majeste by citing the monarchy so Chakarn could continue his master’s degree study at the National Institute of Development Administration.
The source said police were checking to see if the letter Natthapol allegedly wrote to ask NIDA not to punish Chakarn for failing to meet the minimum class attendance was Natthapol's writing.
That process should conclude this week.
