Police have detained a man suspected of posting an offensive remark on a daughter of the Tunku Mahkota of Johor, Tunku Ismail Sultan Ibrahim.

Johor police chief Wan Ahmad Najmuddin Mohd said the 26-year-old man was detained in a house in Jalan Masjid, Wakaf Baru, Kelantan, about 11am yesterday.

"Police seized a SIM card believed used to post the offensive remark," Wan Ahmad said in a statement issued in Johor Baru yesterday.

The arrest followed a police report made on Sept 29 on the abuse of Facebook.

The remark posted was on the status of Tunku Ismail's daughter.

The case is being investigated under Section 233(10(a) of Communications and Multimedia Act 1998.
