I posted before that Johor is a gateway for illegal immigrants who are likely involved in criminal activities.
Here’s more on that from The Star June 4 2011:
More cops to patrol Kota Tinggi
JOHOR BARU: The marine police unit will increase its presence in Kota Tinggi which has been regularly used as the landing point of illegal immigrants.
The district has nine of the 27 routes – locally known as laluan tikus (rat trail) – in the state which are used by human trafficking syndicates to bring in or take out illegal immigrants. The most popular spots are in Tanjung Ayam and Penawar.
Up to June this year, the unit has arrested 299 illegal immigrants of which 230 landed in Kota Tinggi.
The new Marine Police Region 2 commander Asst Comm Zainul Abidin Hasan said that the syndicates’ modus operandi was to constantly change their landing spots.
“The syndicates, which are usually headed by Malaysians, will use rivers or coastal areas along these routes,” he said at a press conference.
ACP Zainul said that apart from illegal immigrants, the syndicates also smuggled contraband cigarettes and liquor.
