Ms Tyrer went missing on Sunday

Karen Tyrer, 28, of Severn Place, Cambridge, was last seen when she left a relative's house in Cambridge at about 1900 GMT on Sunday.

Her family had appealed for her to get in touch, and police had said they were growing "increasingly concerned" for her safety.

However, she contacted Bedfordshire Police overnight.

Ms Tyrer has now retuned to Cambridge where officers will speak to her during the day.
