Two more Scarborough gas stations have been held up and the circumstances sound awfully familiar to a rash of other recent robberies.

Three suspects armed with knives robbed a pair of Esso stations early between 1 and 2 a.m. Sunday, making off with stacks of phone cards and cigarettes.

Police say last night's robberies are linked but they're still working to determine whether these cases are tied to a rash of other gas station robberies in recent weeks.

In those others cases, three suspects with knives targeted gas stations, also stealing phone cards and cigarettes.
