About 10 crime scene investigators and detectives spent hours inside the Hebersham unit yesterday and left with a number of large household objects wrapped in brown paper and tarpaulin.

Police said this was a routine part of their investigations.

A crowd of residents gathered around Kiesha's growing shrine as more police vans and cars arrived.

Crime scene tape was put up and police asked unit block residents for identification before granting them access.

Earlier yesterday Albert Lafaele, who runs a flea market at Hebersham on weekends, gave a statement to Mount Druitt police saying he believed he had seen Kiesha being bashed in the back of a car by a man.

''Backhands first, and then he got up and [he has] gone to town and gave her two punches,'' Mr Lafaele said.

He said the incident happened three or four weekends ago.

A police spokesman said the removal of household goods was part of the investigation.

''As far as the man's [Mr Lafaele] concerned, police are evaluating those remarks,'' he said.

The Maafu family laid a giant pink gorilla at Kiesha's shrine yesterday. ''We were at Woolworths and the lady was throwing it away and they [the kids] asked for it,'' Patrica said of her younger siblings.

''They do mention it [Kiesha's disappearance] sometimes, but it makes them sad because they have friends about the same age.''

Parents who accompanied children to the shrine yesterday said they were worried for their own children's safety.
