Dozens of police officers were out in the city today searching for a missing Newport teenager who was last seen four days ago.

Gwent police say they have "grave concerns" about Nida Ul-Naseer, 18, who was reported missing from her address on Linton Street on Saturday, December 28.

Miss Ul-Naseer, who is of Asian-Pakistani appearance and has long dark hair, was last seen at the address at around 8pm. She was last known to be wearing blue jeans and a black top and is also described as slim and being five feet three inches tall.

More than 40 specially-trained search officers are undertaking enquiries in numerous areas of Newport today and officers will be in the area distributing leaflets and conducting further house to house enquiries.

Search teams were spread out across Newport with a sniffer dog and four horses, which had been called in as additional help due to them being surplus to requirement after the Newport County match was postponed due to the weather.

Teams searched derelict buildings and construction sites in wet conditions and a decision will be made when it goes dark on whether the search will be called off until tomorrow.

Chief inspector Dan Taylor, who is overseeing and co-ordinating the search, said: “We’ve got a distinct police search planned, with upwards of 40 officers conducting it.

“Dogs will be used with small search teams and we’re taking the opportunity to use horses in the fields and on the streets which will be useful because they give a higher view to search teams in fields while they also have a good effect on people wanting to approach officers.

“We and the family are very concerned – it’s very out of character. We are hopeful but we have grave concerns.”

To go missing is particularly out of character for Miss Ul-Naseer, and officers and her family are increasingly concerned for her welfare due to that fact she has not been in contact, especially over the New Year period.

Police are also concerned for the teenager because she has not taken her medication with her and is likely to become anaemic without it.

Anyone with any information is asked to call 101 and quote log number 448 28/12/13.
