Pc Laura Jew was aged 34, had three young children and had worked for West Midlands Police for 13 years.
She began her career as a PCSO in Sandwell in 2008 before becoming a police officer in 2014, being based in Birmingham city centre.

Paying tribute to hear, Chief Superintendent Ian Green, head of Sandwell Police, said: "We’re all very sorry to hear of the death of Pc Laura Jew following a two-year battle with cancer.
"Our thoughts and condolences are with Laura’s family at this sad time. We’re providing all the support we can for them.
"Laura will be remembered as a brave and passionate officer. Whether it was in her roles as a PCSO or Pc, she always put the public first."
Sergeant Kinder Kaur also paid her tribute, saying: "Truly heartbroken to hear one my beautiful friends Laura is no longer with us!
"RIP Officer. One person I trusted deeply to have my back on all the NTE [night-time] shifts."
