Selangor Criminal Investigation Department director Fadzil Ahmat confirmed the matter to FMT, saying police were investigating him under the Arms Act 1960.

He said Jamal was arrested at 1.15pm at the Ampang Puteri Specialist Hospital, where he is being treated.

“There are several others cases for which the suspect is being investigated,” he said, adding that two arrest warrants would be served on Jamal as soon as he is discharged from the hospital.

Police said they arrested him following a report lodged on May 12, after a picture of Jamal brandishing a weapon went viral.

Jamal is best known for leading the “Red Shirts”, organising counter protests to rallies by Bersih 2.0 as well as by Pakatan Harapan supporters.
