A second teenager has been arrested on suspicion of rape and burglary after an intruder was allegedly found in the bedroom of a St Annes care home resident.
The 18-year-old local man was held this morning and remains in custody for questioning.
A 16-year-old boy from Blackpool, who was earlier arrested on suspicion of the same offences, remains released under investigation pending further enquiries.
The intruder - a figure dressed all in black - was allegedly found in a room at the New Thursby Care Home in Clifton Drive North shortly before 5am on Sunday, August 4.
They fled out the same window they got in through, detectives believe, with a major manhunt launched immediately after.
Lancashire Police said in a statement the victim of the alleged attack and their family "are being cared for by professionals and continue to be supported by specialist officers".
It added: "A team of detectives remain committed to the investigation and would urge anyone with information to call 101 quoting log 350 of 4th August."
Liz Hitchen, 39, was the carer who disturbed the intruder – and forced them to flee as she screamed for help.
She said: “They turned and looked at me very slowly. We both looked at each other for a long while. I backed out the door and let out a massive scream that came from deep down.”
Miss Hitchen has worked at the home for five years and said thought her eyes were playing tricks on her as she checked on the resident, who was lying in the dark.
She said: “I stood there at the door and thought, Why are they moving?’ Then I thought it was my eyes playing tricks on me. Then I thought, Or there’s someone behind their bed.’ Then I realised.
“It was horrible. I couldn’t get my head around it when I opened the door.
“With the person standing still, they thought I couldn’t see them because they were wearing all black.”
Police patrols were stepped up in the area in the aftermath of the alleged attack, Det Insp Jamie Lillystone said, while people were warned not to leave their doors and windows unsecured.
Security was also stepped up by bosses at the nearby Clifton Hospital.
Information can be reported to 101. Quote 350 of August 4, 2019.
