The disappearance of a mother who went missing after dropping her daughter at school is being treated as a “potential murder inquiry”, police have said.
Renata Antczak was last seen with her 11-year-old child at Broadcare Primary School, Hull, at 08:45 BST on 25 April.
Police say they have “significant concerns” and believe “some harm may have come to her”.
Her dentist husband Majid Mustafa, 47, has been charged with conspiracy to administer a noxious substance to her.
The 49-year-old Polish national took her daughter to school in the family’s black Mercedes e220 before returning home to Beamsley Way, but police are unsure where the car was driven in between.
Speaking at a press conference earlier, Det Sup Gráinne Casey, of Humberside Police, said: “It has now been 52 days since Renata went missing and we have had no confirmed sightings in this time.
“We are investigating the case as a potential murder.”
However, Det Supt Casey added that police hoped to “find Renata alive and well”.
“The investigation is being conducted by detectives from the major crime team and a senior investigating officer has been appointed. Specialist officers are continuing to support the family.”
She said the force was “not in a position to share any more detail, for operational reasons” but again appealed for information.
Humberside Police said it was continuing to carry out searches around the family home and “in a number of locations”.
Mrs Antczak’s husband was charged as part of the wider police investigation.
