There is no Uber human-trafficking ring associated with Olivia Ambrose’s kidnapping say Cambridge Police. In response to a text message that went viral, police took to Facebook to debunk a theory that’s been going around about a greater conspiracy associated with the 23-year-old woman who was found locked in an apartment in Charlestown Tuesday after three days of searching. “We want the community to be aware that several residents over the last 12+ hours have shared images of a text message that has been circulating around the region,” say police.The text says there is an investigation into a human trafficking ring being operated out of Cambridge by ride-share drivers and is related to the Olivia Ambrose investigation. “As we have communicated to those who have inquired with us, the Cambridge Police Department has no knowledge of any such information or investigation and the information does not appear to have any validity. If anyone has any questions or concerns about any particular public safety matters, we strongly encourage them to contact us directly for any relevant information,” police said. Still they offer tips to ensure safety when using a ride-share services or taxis: 1. If possible, request your ride inside and wait indoors until your driver arrives. 2. Check the license plate, driver photo, and driver name to make sure it matches the app before getting in the car. 3. Ask the rideshare driver who they are picking up. Make the driver say your name first. 4. Don’t take a different ride than the one you selected in the app – even if the driver offers a lower rate. 5. If you’re riding alone, sit in the backseat. You and your driver will have more personal space, and you have an exit if necessary. 6. Share your trip details with family or a friend by tapping “Share status.” They can track your route to make sure you arrive safely. 7. Don’t share your personal contact information with your rideshare driver. All communication should be through the app. 8. If you feel unsafe, trust your gut and call 911.
