  We present the first EVN maps of 6.7 GHz methanol masers of three high-mass
protostar candidates selected from the Torun unbiased survey of the Galactic
plane. A variety of linear and arc like structures was detected. A number of
maser clusters with projected sizes of 20-100 AU show monotonic velocity
gradients. Some of them are roughly perpendicular to the major axes of these
structures and can arise behind shock fronts.
