DARIEN — Several cars were broken into and two other vehicles were stolen in town over the weekend.

In the case of both stolen cars, reported on Monday, the vehicles were left unlocked and the keys were inside.

The first was reported by a Sunnyside Avenue resident around 7 a.m. He told police he went outside and noticed his car, a 2015 gray Audi A4, was missing. He last saw it in his driveway at 10 p.m. on Sunday.

The second incident was reported by a Denehurst Place resident just before 8 a.m. A 2015 gray Nissan Altima was missing. The keys were in the center console. A second Nissan in the driveway, which was also unlocked, was rummaged through.

In addition to the stolen cars, police are investigating four car break-ins.

A Herman Avenue resident went to police headquarters Sunday to report her Toyota Prius had been entered when she was out of the country in February. Taken was a phone charger and some loose change. She believes the car was unlocked.

On Monday, a Sunset Road resident said his unlocked BMW was entered overnight. He noticed the papers in the center console were disturbed and $30 in cash was missing.

A Toyota Highlander belonging to an Allen O’Neil Drive resident was also entered sometime overnight between Sunday and Monday. About $600 was stolen from the center console. The owner told police she could not remember if the car was locked, but police found no signs of a forced entry.

Also on Monday, a Fairfield Avenue resident said her unlocked Subaru, which had been left in the garage with the garage doors open, was entered. Nothing was taken.

The last report came from a Lake Drive resident. She said someone may have entered her unlocked Honda Accord. The contents of the center console were found on the passenger seat, but nothing appeared missing.
