At about 1.30pm on Friday, the unit, whilst on routine patrol, came across three men acting suspiciously.
When the Mobile Squad unit stopped to check on them, all three made a dash for it. The MS13 members pursued on foot and apprehended one of them.
The suspect, from Eastern Highlands, had in his possession a homemade gun, two live bullets and a hood. Upon questioning, he revealed that he and the other two were planning to carry out an armed hold up on vehicles travelling the highway.
He has been detained at Lae Central Police Station where formal charges are being processed.
“Job well done by the Mobile Squad Unit in apprehending this person who could have done harm to the public,” said Lae metropolitan superintendent, Anthony Wagambie Jnr.
“I am further warning youths along the Miles area and in Lae City, do not think of committing such crimes as you will be caught one day. Time will catch up with you.”
