Baltimore County police are investigating a case of vandalism at a pregnancy center in Reisterstown.The Alpha Pregnancy Center was supposed to host office hours Monday but was closed as police investigate vandalism that was reported Saturday morning.The spray-painted message was very intimidating for those who use and support the center. Pictures show someone spray-painted threats against the center that read: "If abortions aren't safe, neither are you." Other messages read: "Not a clinic," and "You're anti-choice and not pro-life."The messages were signed "Jane's Revenge," which is a group that took credit for an arson at a Wisconsin family clinic.There was also evidence that whoever was responsible spray-painted over surveillance cameras, which could hinder the police investigation.While the office was closed Monday, some supporters did stop by, like Bruce Carter, who was leaving donations and another man and his family who were looking for advice on a new pregnancy."Everything's just hateful out there -- hate, hate, hate," said Bruce Carter, who was leaving donations."I'm coming here, it's my first time, just first time right now as my wife is pregnant," said the other man, who asked not to be named.According to its website, the center provides education and support for women facing unplanned pregnancies. A disclaimer on the site reads: "Alpha Pregnancy Center does not offer or refer for pregnancy terminations or birth control. Information is provided as an educational service and should not be relied on as a substitute for professional and/or medical advice."No one from the clinic was available for comment Monday.Anyone with information on the vandalism is asked to call police at 410-307-2020.
