Media reports said Khalid admitted during investigation that he was on a holy war mission in Afghanistan.
The National Justice Movement, a political group that deals with the cases of Bahrainis arrested for alleged terror links, is looking into the details of the latest case.
Former Bahraini terror suspect, Moideen Khan, told the Tribune that no outlawed groups were operating in Bahrain.
He was arrested on several occasions for being part of a sleeper cell in 2004.
Khan and five members were charged with targeting civilians and sensitive places. However, the Constitutional Court and the Supreme Court reportedly dropped the charges.
“Muslims cannot see their brothers being killed in other countries for leading resistance movements. Even the United Nations Charter says there should be defence against oppression,” Khan said
The Bahraini authorities had also arrested eight people for allegedly running a sleeper cell in the country and planning to attack US targets.
Some were released due to lack of substantial evidence while the cases of the others are pending in courts.
