Sin Chew Daily senior reporter Tan Hoon Cheng was released this afternoon and is now back at her house in Bukit Mertajam, Penang.
It is learnt that she was released from the state police headquarters at about 2.30pm, and escorted back to her home by the police.
Previously it was stated that she was taken to federal police headquarters in Bukit Aman, Kuala Lumpur following her arrest last night.
Tan, 33, was arrested at 8.30 last night under the Internal Security Act.
Her release after a 16-hour ISA detention was expected as Home Minister Syed Hamid Albar had earlier said that Tan may be released as early as today.
