Lebanese security and judicial officials say authorities in Beirut are interrogating a man suspected of involvement in the death of a Filipina maid whose body was found stuffed in a freezer in Kuwait.

A senior official with Lebanon's General Security Directorate refused to provide details other than that the man is being held by the agency and undergoing questioning.

A judicial official said yesterday Lebanese citizen Nader Essam Assaf was handed over by Syrian authorities to Lebanon Friday. He added that the man's Syrian wife is in Syria.

Both officials spoke on condition of anonymity because they were not authorized to brief reporters. Mr Assaf and his wife are suspects in the death of Joanna Demafelis.

Kuwaiti police believe Ms Demafelis had been hired by the pair who later left the country, according to local media reports citing police. Authorities found her body when they raided the apartment over an eviction notice.

The discovery of Ms Demafelis's body on February 6 in an abandoned apartment in Kuwait City, where it had reportedly been kept for more than a year, sparked outrage and refocused attention on the tragic plight of poor Filipinas toiling mostly as maids abroad.

It prompted Philippine President Rodrigo Duterte to ban the deployment of new Filipino workers to Kuwait, where many abuses have been reported.

Mr Duterte said Ms Demafelis's body bore torture marks and signs that she was strangled. He said the government is conducting an assessment to "find out the places where we deploy Filipinos and our countrymen suffer brutal treatment and human degradation".

The Philippines is a major labor exporter, with about a tenth of its more than 100 million people working abroad.

The workers have been called national heroes because the income they send home sustains the Southeast Asian nation's economy, accounting for about 10 percent of its annual gross domestic product.
