Both Meiyappan and his father-in-law BCCI Chief N Srinivasan, who were spotted in Kodaikanal earlier in the day, would leave by a chartered flight from Madurai.
They would be accompanied by a four-member legal team, the sources said.
Meiyappan had yesterday sought time till Monday to appear before Mumbai police, hours after they issued summons to him for personal appearance between 11 AM and 5 PM today.
Meiyappan is under the scanner for his proximity to Bollywood actor Vindoo Randhawa, arrested for his alleged association with bookmakers.
Yesterday a four-member team from the Mumbai crime branch had come here looking for Meiyappan and carrying a brief to question him and in case he was not available, deliver summons to him, asking him to appear before the crime branch in Mumbai between 11 AM and 5 PM today.
Since no one was present at his home, a copy of the summons was pasted at his residence and a copy delivered to CSK's office here.
