MART -- Mart Police are trying to get to the source of a recent increase in meth arrests.
They've made four arrests for possession of meth in drug-free zones around the 1100 block of E Texas Avenue and the 600 and 800-block of Limestone.
Mart Police Chief David Monthey tells Fox 44 he believes dealers are targeting high schoolers walking home from school.
The four arrested so far are Michael Allen, 21, Richard Ayliffe, 38, Chad Spears, 40 and Alton York, Jr., 38.
"Unfortunately now, methamphetamines is being cooked so many different ways and manufactured in different chemicals, that depending on where it came from, one dose could kill someone instantly. And obviously if that was to get into the school system that could lead to a very large problem," Monthey said.
Now authorities are trying to figure out if there's a working meth lab inside city limits or if someone is bringing the drug into Mart and distributing it.
