The HEGRA Cherenkov telescope group recently reported an extended unidentified TeV source in the Cyg OB2 region. This is the only unidentified TeV source to date. We obtained a 5 ksec Director's Discretionary Time (DDT) CHANDRA observation of the region of this source. In addition, we secured a near-simultaneous VLA A-configuration observation sensitive to point-like sources. We will present the results of our CHANDRA and VLA follow-up observations of this source. Preliminary analysis indicates that the combined shock of the >2000 O & B stars in Cyg OB2 may be accelerating nuclei to TeV energies, as in the model proposed by Andrei Bykov, SSRv, 99, 317 (2001).
