Officers are carrying out searches around a medical centre in Pitsea as part of their investigation into the disappearance of Madison Wright.
There will be a visible police presence in the area of the Dipple Medical Centre over today as specialist officers and staff carry out this work.
Police ask residents that officers are given the room to do this.
An Essex Police spokesman said: "We are working to keep the disruption to the medical centre itself to a minimum."
Madison was last seen on the morning of July 22 and her disappearance is being treated as murder.
Formal identification of a body found at the Wat Tyler Park on 30 July is yet to be confirmed but police are continuing to provide specialist support to Madison’s family.
Garry Bennett, 36, of Caister Drive, Pitsea, has been charged with Madison’s murder and he is next due to appear at Basildon Crown Court on Friday 23 September.
Anyone with any information, who officers have not yet spoken to is encouraged to contact them.
