As Mumbai observed the 17th anniversary of the 26/11 terror attacks, a memorial installed in Kalyan in 2009 to honour five police personnel killed in the assault has vanished from its spot.

While a senior police officer said the structure had become unsafe after a speeding vehicle crashed into it, officials from the Kalyan-Dombivli Municipal Corporation  insist the junction is undergoing major redevelopment under the SATIS project and the memorial may have been removed during preliminary work an under-construction flyover.
