Erika is described as eastern European, 4ft 11in, slim, with long, brown straight hair, brown eyes
Investigators are searching for Erika in Darnall, while ''various lines of investigation'' have led to police looking for her in Bradford. It is believed she could be staying with friends in the city.
Speaking yesterday, Detective Inspector Helen Tate said: ''We have had various sightings of Erika today, but as of yet, none have been confirmed.
''It is out of character for Erika to be away from home for so long. We are getting increasingly concerned for her welfare as time goes on.
''Erika is only 13, she is young and a normal teenager, who listens to music and spends time with her family and friends. We want her to return safe and well.
''We have around 50 police officers and staff working hard day and night in a bid to find her.
''We've received dozens of calls from members of the public, some in West Yorkshire and some to us here in Sheffield. Please keep these calls coming in."
She added: "'Erika has two younger siblings, a brother and a sister, they, along with her parents are distraught at her disappearance.
''Erika, if you are reading this, please let us know you are okay. You're not in any trouble; we just need to know you are safe and well. ''
Erika is described as eastern European, 4ft 11in, slim, with long, dark brown straight hair and brown eyes. She was last seen on August 5 at around 4pm on Poole Road wearing blue jeans, a pink polo-shirt and a silver-grey jacket.Suggest a correction
