An investigation has been launched after chemical items of concern were found within a property in Dalkeith.
Around 2.10pm on Tuesday 20th November, officers were called to support the Scottish Ambulance Service as they attended an address in Elmfield Park.
A 19-year-old man was taken to hospital with serious, but not life-threatening, injuries and officers are not currently looking for anyone else in connection with this.
He has since been arrested following a breach of the peace and the assault of two police officers, and is due to appear at Edinburgh Sheriff Court today (Wednesday 21 November).
The Scottish Fire & Rescue Service and EOD were called to support officers at the address.
Police said that the community can expect to see officers and other emergency services personnel at the property over the coming days.
Chief Inspector Kenny Simpson, Area Commander for Midlothian, said: “I appreciate the disruption and concern that the significant emergency service activity may have caused to local residents.
“However, following specialist examination, I want to reassure people that there is not believed to be any immediate risk to the public.
“Be assured that we continue to work with colleagues in specialist areas and outwith Police Scotland as we establish the nature of these items and their purpose.
“Anyone who has concerns or information which may be relevant can speak to an officers in the area or contact Police Scotland on 101, quoting incident number 1853 of 20th November.”
