Sowore left the Washington Dulles International Airport at 6.14 EDT and arrived in Lagos at around 9.43 WAT.
The development comes after it was learnt in early September that the DSS had instructed airport security and immigration authorities to intercept and detain Sowore whenever he returns to the country.
The directive to arrest Sowore was issued by the newly appointed DSS Director-General, Adeola Ajayi, due to his prominent role in the recent 10-day #EndBadGovernance protests.
