Police are making inquiries into both incidents, including working to identify and locate the alleged offenders.
“These alleged offenders are engaging with people on these apps with the intention of meeting them in quiet areas at night-time to attack them,” Robertson said.
“Not only are they taking advantage of people’s trust, but they are planning these attacks with the intention to seriously injure these people.
“We urge anybody who is planning to meet someone from a dating app to choose a location which is public, or well-lit at night, as well as letting someone trusted know your plans and movements.”
Police are keen to hear from anybody who has information regarding these assaults, or anyone who was in the Queens Park area between 6pm and 4am from Friday, May 8 to Sunday, May 10.
