We present the detection of OH maser emission associated with the H2O masers recently found in the Galactic center by Levine et al. and by Yusef-Zadeh & Mehringer. The 1612 MHz OH masers were found in high-sensitivity maps created by combining 17 VLA observations taken by van Langevelde et al. as well as in new observations with the ATCA. Both Levine et al. and Yusef-Zadeh & Mehringer consider the H2O emission to be clues for recent massive star formation, by associating it with a supergiant and an H II region. The newly found OH masers show the typical double-peaked spectra for evolved oxygen-rich stars and do not stand out among other OH/IR stars in this region, either in H2O or OH maser characteristics. We conclude that the H2O maser detections are associated with evolved, low- to intermediate-mass stars, and that these H2O masers thus cannot be regarded as signposts for massive young stars or star-forming regions.
