Sin Chew Daily journalist Tan Hoon Cheng has been arrested today under the Internal Security Act at 8.30pm at her home in Bukit Mertajam, Penang.
She is the second person to be arrested today under the tough security law which allows for detention without trial.
It is learnt that she has been taken by the police to the Penang police headquarters.
Tan had reported that local Umno chieftain Ahmad Ismail had allegedly said that Chinese Malaysians are “squatters” in the country.
Her report sparked a nationwide outcry, resulting in Ahmad beingsuspended by Umno for three years after an emergency meeting on Wednesday.
Sin Chew had three days ago came out strongly to defend Tan, who was accused by Ahmad for misreporting his comments.
It is unclear whether Ahmad, who remained defiant despite being slapped with the suspension, has also been detained.
