Fire fighters from Croydon have been sent to west London to help police search for Alice Gross.
The 14-year-old went missing on August 28 and was last seen walking alone on the Grand Union Canal tow path in the direction of the River Thames just after 4.20pm that day.
London Fire Brigade (LFB) confirmed that fire engines and crews from Croydon stations were sent to assist police in the search for Alice at 9.30am this morning.
An LFB spokeswoman said: "London Fire Brigade's Urban Search and Rescue crews are assisting the Metropolitan Police Service with their search for the missing teenage Alice Gross.
"Crews are using specialist search, cutting and winching equipment to clear the area of heavy debris like fallen trees to ensure that the police can conduct their investigation safely and access difficult to reach areas."
Today police searched an area in Elthorne Park but following a full assessment they have determined the area is not of relevance to the investigation into Alice's disappearance.
