Police officers are investigating a number of burglaries in the Narberth, St Clears and Haverfordwest areas which were reported on Wednesday, January 22.
It is reported that damage has been caused to the properties and valuable items taken, including cash, jewellery and power tools.
Officers believe these incidents are linked.
Detective Inspector Owen Lock said: "We would like to reassure members of the public that enquiries are ongoing and we’re committed to catching those responsible.
“I would also ask that any suspicious people/activities are reported to the police. Remember, we can’t act on something if we don’t know about it.
“No matter how insignificant it may seem, please report all suspicious activity to police immediately, and don’t assume someone else would have notified us.”
Officers are advising residents and second-home owners to check their vacant properties and to ensure it's secure and valuables are protectively marked and locked away.
